Nexus 7 increase color saturation kernel available? - Nexus 7 Q&A, Help & Troubleshooting

Is there any kernel available for nexus 7 to increase color saturation of the screen? Although my N7 screen looks fine, I am used to Amoled from my phone, so it would be great if I can increase the saturation. It would look awesome with games.
I tried this app: https://play.google.com/store/apps/details?id=com.netmanslab.sa
but doesn't help at all. No option to make it more saturated, but only less saturated.
Thanks!

Hm..I don't think that app is the one i need..
I don't feel that the screen is washed out or anything like that in general. BUT what I really want is by rooting it and maybe increase the saturation so that it's more comparable to my AMOLED screen on my phone. I know there is an app for Nexus 4 that does exactly this, but I asked the dev if it would work on other devices as well, and he didn't reply at all. This was quite awhile ago actually..
BTW I haven't rooted my N7 yet and the only reason I may root is to increase color saturation.
Maybe someone else has more idea?

Isn't the opposite of washed out colors is saturated colors? Or am I just not understanding what you're wanting?
This should help with color saturation because washed out colors = desaturation. It's the only app I've seen.

I re-read my comment, it seems fine..what didn't u understand? um..you know that AMOLED (the one on my phone) is extremely saturated display right? so I'm used to the display, but N7 display isn't too bad (not very washed out in GENERAL, as IPS is usually like this), but compared to AMOLED it IS washed out. Most people would be fine with this IPS display on N7, and I'm okay too actually, but it would be awesome if I can increase the color saturation to make it more saturated, closer to AMOLED.
Hope you understand my question..
so it's not the Prism I'm talking about. I want to increase the saturation entirely. Prism I heard only makes the screen washed out for like 30 seconds while watching movies or something. I don't really have any problem with this btw..
Thanks.

The problem is that it stays on. It helps with color saturation and contrast, it's the only thing I've seen. You can try messing with the colors in CM and such but I doubt you are going to get anywhere.

Holy Grab BAgs!!! The new 2.3.3 fixed my purplish tint issue!

Wow too my surprise, after installing the new update, I noticed right off the colors has been calibrated correctly! No more purplish in certain shades of grays now!
Sent from my Nexus S
2.3.3 also fixed my overly bright screen too. I used to have my NS always set on the lowest brightness setting and I still felt that it was too bright.
Yeah it did seem to improve the brightness as well. I like the new settings.

You guys don't think its too yellowish now??
I do a bit of photography and have a colour corrected wide gamut monitor I use for retouching.
To my eyes, when looking at the same photography on both devices, the new colour temperature is much closer to 'correct' than the old one was. Not perfect but much more preferable to me.
so maybe all the complaining people have been doing is just their eyes not used to what the screen "should" look like

That is 100% correct. My girlfriend is a professional photographer and she even commented on how much better it looks.

I know that when I first bought my Datacolor Spyder colorimeter to calibrate my monitor it took a while to get used to the results. Much less "in your face" than before, but much closer to natural.
I exchanged my first Nexus S because the screen was too blue/purple. The second one was slightly less purple. But the new color profile got rid of all the purpleness

on modaco r11 "2.3.2" and the colors are awesome , i had the purple tint on dark gray areas but its all gone now .
can someone compare this with the colors on 2.3.3 ?
I like the new colors it looks now great!!!
I noticed the colour difference immediately as well. It actually felt weird to me, I was really used to the purplish colour in the UI. Feels very grey. Not complaining though if this is how it should have been, but feels weird.
I for one do not like the new colors. They look too washed out and gray.
The Crispness is gone. Whites are now yellowish. I am not a fan. I did a comparison with a friends NS side by side his with 2.3.2 and mine with 2.3.3. and there is a difference and 2.3.2. looked better. This could be "the correct color" as has been stated but that does not mean it looks better. I have never noticed a purplish tint before and even looking at my friends NS with 2.3.2. I still do not see it.

Same here. Looking at it again (2 Nexus S side by side) the one with 2.3.3 really seems washed out.
I did notice an occasional purplish tint on 2.3.2, but mostly from different viewing angles, less so when looking straight on at the screen. It never bothered me. The overall color scheme was also a bit cool, with more blues coming through. I've read that because blue LEDs in AMOLED screens wear out quicker, often they are overemphasized at first and will fade over time. I thought this might have been the explanation.
I definitely noticed a color change after updating to 2.3.3. At first it was very bothersome. The colors do seem to be washed out and the whites seem just a tad yellow. But I can see how this may be more accurate as the previous color scheme was overly cool. Maybe we tend to prefer a cooler color temperature. The new one will take some getting used to. Blue is a "comfort color" after all.
Blue appears brighter to the human eye despite the actual lumen output being similar. It's like those custom bulbs that some people like to put on their honda civics or whatever, the blue/purple looking ones. Yea they "look" bright but they actually output less light than the standard yellowish bulbs.
Anyway, being an avid photographer and spending hours tweaking my plasma TV's colors, warmer colors are more natural to the human eye and most people jack up the blues to make things look more contrasty or sharp, which in my opinion is too harsh and fake. Even the iPhone 4 screen is tinted blue to make whites appear brighter. Then again, some HTC screens are so red tinted it's ridiculous, so in the end, download the color calibration app and tweak it according to your liking.

i would say the voodoo fix isnt as "extreme" as 2.3.3

Colors aren't as vibrant as I'd hoped.. Any solution?

I'm about to trade for a GS3 that's how bad it is.. I personally love the over-saturated screen on the galaxy s3, as well as the ability to have black blacks because of amoled, but love the fastness of this phone. Can I root and change the colors?
you mean as saturated? Colors are as realistic as they can be.
Wait for a kernel with colour control? (IIRC colour control is possible with the N4, correct me if I'm wrong)
In the meantime you'll likely get used to the new screen.
No don't think you can edit the colors like you can with an amoled screen

Okay thanks, Like the colors on the iPhone 5 look even better and more vibrant and I thought the screens were very similar?
Most people here are going to bash you with the "saturated" thing.
Personally I agree with you. There IS a place between washed out and over saturated. This phone fits closer to Washed out (not as bad as HTC screens, but it could stand to be a little brighter and more vivid). The colors ARE dull. The Lumia 920 is a great example of the middle factor. No where near as saturated as the S3 screen, but still bright and vivid colors while holding most of the true color. The whites on this phone are not even close to true also, which I think adds to making the other colors look more dull.
My opinion of course, everyone has their own personal taste. I get bashed all the time for not liking HTC's dull and lifeless screens, but to each their own.
The screen is a bit dull, especially at some of the lower brightness settings provided by Auto Brightness. Of course it will look way less saturated than an AMOLED screen, but I don't think that's the issue at hand here. I feel that it's more so a gamma and contrast issue rather than one of color reproduction, and that on these IPS displays the contrast is much more a factor of brightness than on AMOLED.
Compared to my calibrated IPS displays, the colors are decently accurate but the contrast is much lower.
Colors don't look washed to me at all, coming from a GNex also which is obviously very over saturated yet I'm still really enjoying this screen. I probably just don't have the experience with well calibrated screens to know if mine is washed out but the colors are pretty vibrant to me.
It did seem dull at first (I came from an sgs2) but now I've got used to it and actually I'm starting to prefer the more natural look the colours give...

Oh yeah, over-satuation is so cool, nearly as cool as a pentile-matrix, where you can see the space between the subpixels.

No need to attack him. He clearly stated that it was his personal preference, not "OMG AMOLED RULEZ". He can like whatever type he wants.
The blacks are just bad. The colors I can live with.

Why colors are not vivid in this screen

Why colors are not vivid in this screen they look a little wached out
What u guys think?
They don't appear as oversaturated as the ipad 3/4 or OLED screens but it looks so bright that it makes up for it. I know the actual nit ratings are not the highest but this thing looks BRIGHT on the auto setting.
With the brightness all the way up it seems washed out. Just turn the brightness down. It's overkill for the most part, and seriously cuts down the battery life. Compared to my galaxy nexus, the blacks aren't nearly as good, but I'd say the color is more natural. Cheers.
When more kernels are released i'm sure there will be color controls. I'm personally waiting for franco kernel. He just posted on his google+ inquirying about releasing a test version of his kernel. should not be too long until we have the ability to change gamma and color density patience!

Thats cause this uses an actual LCD screen, unlike the Galaxy nexus. Honestly the blacks are one of the only decent things about the GNex screen. Custom kernels had to fix some major color issues with most people's devices. And as the person above me said, we will soon have kernels for this device too that allow color, contrast, and gamma options so anyone who is unsatisfied with colors at default can tweak their settings around.

I second this. Stock colors on the gnex make it look like a cigar stain. Think I stole that line from somewhere. Anyway they are bad. I've tweaked the colors on my gnex and now the diff between the two devices is less. I personally like oled, but the n10 screen IMHO is far more color accurate which may at times make it seem washed out.
Its kind of like too much bass. An untrained ear might say too much bass sounds better then a flat curve.

The screen produces a very poor rendition of the NTSC colour gamut. I have professionally calibrated equipment at home to compare. Gray scale is good. Gamma is OK. Color accuracy is poor. Very antique looking. This is similar to how Panasonic used to calibrate their displays. The contrast is average. Overall the screen is simply mediocre with minimal glaring issues. This screen isn't for showing off; its for getting work done. Bright, sharp, and bland looking. Hopefully a dev unlocks some mdnie hacks that offer control over the displays calibration. A couple tweaks could definitely improve the perceived contrast and improve color accuracy. I've had a number of nexus devices over the years. They're very no frills. So I don't think we'll see many tools for improving the screen. Maybe some wonky color gamma tweaks.
Supercurio I'm calling you out for some assistance.

BTW I have a galaxy nexus with an amoled display. With some adjustments its a superb screen. The gamma is too high and colours are over saturated, however the colour rendition is far more accurate than the nexus 10. The blues and reds on the nexus 10 are way off the mark. Blues are more cyan, they are washed out, not deep enough. The reds are very under saturated. The greens are muddy, slightly brown. Yellows are over saturated and magenta is slightly under saturated. The display just doesn't compare to the new iPad in the slightest. Oddly enough, sharpness is the least important display characteristic for a quality display. Humans are much more sensitive to contrast and colour. The nexus 10 display has its priorities mixed up. On the other hand, I still love this thing and wouldn't trade it for any other tablet on the market. Its graphics performance is beastly and just outclasses most other tablets in regards to build quality.

There's an app called Screen Adjuster to adjust rgb and contrast. Root required. I wonder if that may help. I'm not rooted so I can't really try it. And I may end up returning it so didn't wanna muck with it for now.

Calling the ipad 4 oversaturated is just ignorant.
Not sure if its placebo but I updated to 4.2.1 and my build # is JOP40D and the screen isnt as dull anymore. Blacks are darker although still not as dark as my tf700. Anyone else notice this after the update?

Are you using sRGB?

Hey, just wondering how many are using the sRGB screen mode and if you notice any effects on battery life with it on.
I'm not, its no replacement for an LCD, just makes the screen look dull and washed out imo.

I am, I can't stand the poor color representation of amoled. Do love the pure blacks though. Switching the color mode goes someway in helping, I prefer it.
Nope, not at all. Colors look horrible in my opinion.
Same here, sRGB looks like a cheap screen with dull and boring colors.
I would but it doesn't stick over reboots for me.

I would have to agree, the amoled screen looks way over saturated in my opinion especially when the brightness is turned up
I do photo & video production work, and to be honest...as someone who knows at a glance when colors are saturated or not, I do prefer non-srgb look. I think it's a mix of the Amoled display's deep blacks, the high resolution, and the color point. It's pretty pleasing to the eyes.
Did not like the sRGB look, so not using it.
Does anyone know how to make Tasker automatically enable sRGB mode?
Notwithstanding "looks", dosa sRGB save battery?

It looks really bad in my opinion. That sRGB on AMOLED looks way washed out than on LCD. I keep it default. Also it doesn't affect the battery at least according in my experience. I tested the "Basic" mode on S6 edge+ which is supposed to be the sRGB of Samsung phones and it looks same as the one on N6P and there it also didn't affect the battery.

Saturating AMOLED is the same as compressed HiRes Audio. You lose detail in the subtleties of the original. No bueno

Pixel 2 XL NEW SATURATED Display Mode Nov UPDATE - Comparison vs NOTE 8 vs Pixel XL

Google releases November security patch that includes new display color modes (Boosted, Natural, Saturated) for the Pixel 2 XL to help with the screen color saturation issues/problems. Update includes fixes for screen burn-in and the ear piece clicking noises. Love that Google added this options, in that way people that want accurate colors can use the "Natural" mode, those custom to Samsung's "saturated" (candy) colors, can now pick "Saturated" mode. All about having choices.

That's caused by the polarized layer afaik, not sure how saturation would change that
I couldn't really notice a difference... Will see when I get the phone and update is applied.
But I was happy with the colours when I looked at it in the shops..
Wasn't so impressed with the blue screen off axis. 1 was spot on, 2 were shockingly bad.

I don't like the saturated mode, colors are too bright and white is more red now. Sticking with the original boosted mode, I like the more natural colors.
Oh, and no help to the blue shift since that is hardware based.
Man I can't wait for kcal.

Looks terrible to me. Yellow whites and colors are extremely off to me. Boosted is my go to.
Yup after using the phone in saturated mode for two days I'm back with the boosted mode. Saturated mode is REALLY saturated. I find it even more saturated than the Note 8.
Too hard to tell in a video, but in person saturated makes everything pop like it's a Samsung panel. Pretty nice, I love it when I'm not in the mood for the most accurate colors.
I definitely appreciate the update Google.
I've found that the saturated mode is great when navigating android, but when looking at real life pictures, boosted is best. I think we need a slider to fine tune it to our own likings. I think we need a little more saturation than boosted, but less than saturated.
Has anyone else noticed that when you look at a picture and angle it for the blue tint it actually looks better? I took a picture of my daughter and the saturation makes her face look red, but when i tilt it, the extra blue overlayed on top of it looks almost perfect!

I agree! With saturated mode i think they are also changing the color temperature because there's sortof on dark orangish or reddish tint over everything now where before it was more of a bluish tint. We need the slider!

I noticed this too, saturated mode is good but it is a bit too red for me and the colors do make pictures look unnatural but I managed to mitigate some of that with KCAL using root and snoke kernel. I turned down the red and green a bit so now it has a blue hue closer to the natural setting. I also turned down the saturation a bit.
Directly from Google; Further enhancements will be included in our planned December software update and on an ongoing basis thereafter. Our goal is for your Pixel phone to get more useful and delightful over time.
So maybe we will get a slider after all? We'll find out soon enough.
I still like boosted the best.

I'm loving saturated mode. Besides the whites being more reddish instead of blue it's pretty close to what my OG Pixel XL was.
If you guys want to know what really colors should look like either buy or find a monitor with 100% coverage on sRGB range and which are properly factory calibrated.
http://www.trustedreviews.com/news/monitor-colour-spaces-adobergb-srgb-2949078
I am 100% the pixel or for that matter any phone out there lacks realistic representation of colors, and therefore images.
Whites should be at 6500k.
Also be wary of your photos you take, what you see could be severely oversaturated but in reality its probably not so good or vivid.
To this date, there is no phone with realistic colors.
Cost and people being addicted to neon colors could be reasons.
So is boosted the exact same as "vivid colors" or is it a little bit better?
