The Nexus One is capable of using 16M we all know this!
But the stock gallery aka 3DGallery is not only limited to 65k but also limits the wallpapers set there to 65k, resulting with color banding and losing color richness.
I found a very helpfull app for free on the Market: Wallpaper Set and Save You browse for a wallpapers folder,then choose a wallpaper and set it!
Voila! you have now a rich 16m colors wallpaper of your choice, no more color banding
Wow, thank you! I didn't know there was a diffference between setting in gallery and WS&S.
I can confirm that there is a better color representation when setting in WS&S. It's not drastic, but it does remove the abrupt color change spots (color banding).
+1!
I don't know if anyone knows this, but on stock launcher, as well as Helix the home screens run a lot faster without a wallpaper (versus Live Wallpaper, or just static image).
To disable wallpapers just set the wall paper as a live wallpaper and open your favorite task manager app. End the process of just the live wallpaper, and not of the live wallpaper chooser. For most cases it should close out only the wallpaper and doesn't apply the default Nexus neural network live wallpaper. You should then have speeds comparable to Home++'s launcher, etc.
Of course once you reboot your phone or allow the wallpaper to reopen you'll lose the setting.

where can i get this wallpaper at?
btw have you guys seen the bokeh wallpaper? i personally love it and i think its better than the desire live wallpaper (i flashed the sense rom just to rip the wall from the rom but i am having trouble installing. its apk if you guys wanna try it)
Has anyone noticed that wallpapers are still banding with this app now? It used to work perfectly, but in the past few months (maybe since froyo? not sure) high gradient wallpapers are banding again, such as the HTC Desire rainbow, grey-to-white snow sceneries, windows7 betta fish wallpaper, etc. Anyone have any suggestions on how to make my wallpapers stop banding again?

You probably already found this somewhere else since it's been so long, but here it is. Sorry for the delay.
No problems at all, all the pics are working with 16m colors and no banding,it has nothing to do with FW anyway,the N1 is capable of 16m but it's the HTC heritage app ''gallery'' that is limited.
Use only Wallpapers Set and Save from the Market not the gallery or gallery 3D

Hello,
I've run BiffMod-HD2 Vanilla Froyo and am currently running MDJ's CyanogenMod 7 Gingerbread on my HD2.
In both instances, UI elements and apps with gradients look low-quality and have step banding.
I think it may be only with PNG files used in backgrounds, buttons, and widgets etc. Anyway, its ugly. Does anybody know why this is and how to fix it?
I took screenshots, but they the gradients look perfectly smooth when I view them on my computer.
I'm having the same issue. It's happened on every ROM I've flashed. Hopefully someone will provide some insight here.
Does anybody know?
Same problem. I think, it happens because HD2 screen is 65k colours only, and Windows Mobile UI is adapted for this mode. But Android was designed for AMOLED screens with millions of colours...

Yes the banding is due to 65K color limitation to the HD2 screen. I guess the banding disappears while using the Launcher Pro.

Is it hardware or software limitation? Any way to unlock another color modes?
It is not hardware limitations. There is already another thread with a ton of info. If you want banding to go away, use LauncherPro WITHOUT a live wallpaper until a permanent fix is implemented.

Thanks. I didn't think it was because of the screen's color limitations. If so you would see banding in JPGs and video. The banding only seems to appear on PNG files, which happen to be used in most graphical UI elements.

Just tried Launcher Pro and I still have the same problem. I used to use Launcher Pro on BiffMod Froyo and the same thing. The problem presists with 2.2 Launcher, 2.3 Launcher, Zeam, ADW, and Launcher Pro.
And its not only in Widgets. It can be seen in most UI buttons, the call screen, and most predominantly in the voice command pop up. That thing looks like a coin would shoot out if Mario hit it with his fist.

The banding remains elsewhere, but using launcherpro, the banding disappears on the widgets and wallpaper. AGAIN YOU CAN NOT USE A LIVE WALLPAPER with launcerpro or else banding will appear. Then under advanced settings, select high quality scrolling so you dont see banding while scrolling.
I'm using LauncherPro with PureGingerbread this works for me.

I don't use live wallpapers. Still doesn't work for me. Oh well. Using Launcher Pro is really just. Bandaid anyway. The root of the problem is still unknown, at least to me and most people here.

Awesome. Thank you.
EDIT: Banding issue resolved via a market app. Yellow still brownish though.
This might be why all of the colors seem... off. I tested the same wallpapers on my captivate and on my atrix. The atrix shows HUGE HUGE HUGE amounts of banding in each and every wallpaper. This is generally a sign that its limited in color range. Both phones are rated as having 16million colors (24 bit), however, I believe the Atrix is more in line with the Evo and only showing 65k colors (16 bit). Both the Evo and Atrix have the same banding in their picture display due to lack of color depth.
Either this is a major misprint on their specs, or they messed up their kernel somewhere along the line? I am not sure what coding could be off with this but could this be our possible color issue?
Unless there is some other reason for this, this phone SURELY isnt displaying 16 million colors. My iPhone has no banding whatsoever on any of the same wallpapers as well.
try setting the wallpaper with an app called wallpaper set and save in the market. do you still see the banding?

Ill try it, but there is banding all over the UI. Look at the market menus etc. Its everywhere.
Ok that did get rid of the banding on the wallpaper - thank you for clearing that up. Yellow still having issues though.
yellow is an issue with the atrix screen itself. Google just pushed an update for the nexus s that tweaks the colors a bit so I suppose it may be possible to do the same on the atrix. it might be due to the RGBW subpixels of the atrix screen though.

Hey guys,
I've had android on my HD2 for a couple of months now and it's great, but the thing I hate (on any device, let alone one I'm using all the time) is color banding. If you don't know what color banding is, it's when a display incorrectly renders a gradient between two colors - for an example, click here.
LCD screens are much less prone to color banding than AMOLED, but the HD2's screen is not designed to display the ammount of colors android requires, so many things in the UI have color banding.
However, I've noticed a difference between ROMs - some have banding worse than others, so there must be some way to fix it.
I'm talking specifically about Desire HD ROMs, because that is my experience. The default wallpaper in Imilka's ROMs appears badly banded, as does the UI, whereas in Rafpigna and CMYLXGO's ROMs, the same exact wallpaper image appears smooth and incredibly high resolution.
So my question is - how do you format a background image to cut down on banding? How can the same image appear badly banded on one ROM and smooth on another?
My theory from other phones (HTC Legend, HTC Desire): wallpapers applied from the "HTC Wallpapers" tab always appear smooth with no color banding. Therefore, these images are formatted in such a way as to minimalise the eye-raping. If somebody knows how to duplicate this with other images, that might go a long way to solving the problem
Does anybody know anything about this? It's not a major issue, but it's an annoying one
Cheers
It's hardware, not software. The screen on the Leo has only 256k colors, the same as a GIF image.

It's actually a 65k screen. Also, a GIF does not have 256k colours. It has 256.
So yes, the lack of colour is what causes the banding, this can be helped by enabling dithering which is available on CM7 which is I guess why you see differences on different ROMs.
I've never used a CM ROM and I've noticed differences across roms. I understand there are hardware limitations, but as I said in the OP, there are differences between the same image across different ROMs in regards to wallpapers and UI elements, and there has to be some kind of way to replicate that/format an image to look better

Thanks heaps for that, very helpful post.
I've discovered a (partial) solution for color banding in wallpapers on HTC ROMs.
If a wallpaper is applied through the image gallery, it appears without dithering. But if a wallpaper is applied through HTC's stock wallpapers folder, it is dithered. So, to fix this, I took the image I wanted to use as my wallpaper, put it in the system/customize/resources folder of my ROM.zip file, named it one of the default HTC wallpapers "HTC_wallpaper_04.jpg" (after saving it as a JPG) and the image is now smooth with no noticeable gradients.
If anybody else has a chunky wallpaper and you're using an HTC based ROM, this fix should work for you.
Ones that are scaled for the mobile displays and not the desktop/tablet ones? Been looking to switch up my wallpaper a bit, but the ones I grab off the Internet just don't look good on the phone the majority of the time.

For the moment I am just rotating & cropping desktop 1440p wallpaper in Nova Launcher. If there are more 1080X1920 portrait wall paper I'd like to see them.
Try ZEDGE

I use an app called ZEDGE - you can download and install hundreds (thousands) of Hi Definition, awesome quality Wall Papers - I personally like wall papers that have a sort of 3d effect - with depth to the image - and I found quite a few from ZEDGE - You will find it here;
https://play.google.com/store/apps/details?id=net.zedge.android&feature=nav_result#?t=W251bGwsMSwyLDNd
As an added bonus, you can also download free ringtones, notifications and alarms. I love it - good luck - hope it works for you.
If I have helped, don't forget to say thanks.
I posted in the themes sub forums that the correct resolution for the phone is 2160x1920. This results in the most detailed backgrounds. Personally I've found there to be a lack of wallpapers for my taste in this resolution so I resorted to the slightly more common 2560x1920 wallpapers. It crops wide, but height is perfect.

I found a nice website with a lot of 2160X1920 wallpaper for GS4 here :http://www.mygalaxys4wallpaper.com/gallery.php?gallery_id=21_Space&paging=0
Just updated my own Wallpaper.
pics work too; i snapped this one the other day, desaturated it, and cropped it.
I find good pictures then I make the HD background. For best support I crop and scale them to 1920x1920. Then it works for vertical and horizontal screen without anomalies.

Well, to get full HD wallpapers I can only recommend http://fhdwallpapers.weebly.com/ . The site is easy to use and browse, and it's commited to providing only vertical (portrait) 1080p wallpapers for mobiles; some high quality stuff there actually.
If you want full HD wallpapers with the status bar shadow effect (my personal favorite), then go to http://fhdwallpapers.weebly.com/shadows.html .
