Change the blinking color?

You know how ...
When your charging the Shadow, it show's an orange light.
When bluetooth is enabled, it's a blue light.
And when it's not charging, it's a green light.
Is there a registry hack or anything to change the light to other colors such as red, pink, etc?

The leds are only that color and can not create any other color combination other than what it is [orange (charging), red (Batt very low), blue (bluetooth), or green (radio signal)]. There are two color leds available which basicaly are two leds built into one, for example on the Shadow, one led having orange and red and the other having green and blue. Getting a bit technical, to make custom colors it would take a RGB (Red, Blue, Green) led that would have to have individual control of the three colors to create any color you can think of like on an lcd monitor. Hope this answers your question.

LED Control

Just rooted me phone. Thanks to everyone who contributed to it!
With root, do we have control over the led color notifications finally? Or does that require more semantics?
Moto Droid's LED notifier is RGB. DroidINC has to have something similar right, because we get Red, Green, and Orange..unless they someone how have three colors in that tiny hole...

I don't understand... what does the study of words and the meaning herein have to do with LED control? Did I miss something?

What do you mean LED color? The LED flash is the only LEDs on the phone and they are one color. You can swap it out for a custom color leds and put them in the place of the dual flash LEDs but other than that you can not change the color.

Oh, let's not argue about semantics
I read somewhere other than XDA that HTC had released the Incredible devices source code which, if true, will lead to all kinds of devices-level mods. I personally would like to see the soft button backlights be dimmeable, or individual controllable for different kinds notifications, or possible a scrolling/marquee style effect so it looks like KITT is in charge ehehe.

He's talking about the notification LED on the front of the phone.
and OP there's nothing out that I'm aware of as of now.

I don't think any software modification would allow you to change the color of the notification LED at the top or the LEDs at the bottom (Home, menu, etc). However, I don't know anything about LED technology to argue my thought(s). I assuming that whatever color bulb they put in there is what you get.
Don't get me wrong, I would love to have the bottom buttons a red color to match the top speaker/camera areas because the phone would look absolutely badass but I'm not about to pry the screen off or take the phone apart to do it.

Correct me if I'm wrong, but the Dinc has at least a green and red LED for notifications. The Moto Droid however has RGB so you can pretty much make any color appear. That is also why there are a lot of options in apps like Handcent and Missed Call.

Sorry for the confusion, all. But yeah, I was referring to the LED notification on the front.
The LED flash on the back- is a bulb which can only push out white. But the one in the front pushes out Red, Green, and Orange. And with the moto droid, you could manipulate color notifications with different programs..
so my question is more of- is it software that locks those colors or hardware that does... thanks for clarifying my question-jrkrush2112

I suspect the notification LED in the Dinc is a tri-color which gives you red, green and a form of brown which looks like amber. It is not a RGB LED like in the Moto Droid.
So you already have the colors that are available.

It's most likely a mix of both. The hardware portion is the fact that we don't have an RGB LED like the droid, and software is just what options are pre-set. We will be able to change the colors for notifications, but we are limited in options.

[Q] Notification Light No Red RGB values

I broke my screen a few days ago and had it taken in to be replaced. A few hours after receiving it I noticed the LED was blinking, but in strange colors different than those I set in Light Flow. The normally white notification is now cyan, yellow is now green, purple is blue. Red however doesn't display at all, so it seems that the red portion of the RGB scale is not functioning. Does anybody know what during the screen repair process might be causing this to happen? I'm almost certain its not software related as prior to having it repaired the LED was working correctly. Thanks!

There's a kind of filter for the LED on the display, not all replacement parts come with it and it's pretty easy to overlook.

There does seem to be a blue hue around the notification light area when held in the light... So could it be that this filter was mistakenly left on the old screen, instead of transferred to the new part? Or is it something attached to the screen that can't be moved from one part to the other?

It wound up being a damaged LED light

An issue I never understood (Ultra power saving mode)

Hi there !
Just call me a noob - but I don't understand a feature of that "Ultra power saving mode". It's the black and white display.
If we dare to ignore the special features of a pentile matrix, it comes down to a pixel consisting of three subpixels: Red, Green, Blue (RGB).
To display greyscales of the color "white" , we need ALL THREE subpixels illuminated: [•••]
For displaying the colors "red", "green" or "blue" we'd need just ONE subpixel illuminated: [•] or [•] or [•]
Clear so far ? - Well.
AMOLED displays control each subpixel directly - many subpixels illuminated = high energy drain, few subpixels illuminated = low energy drain.
So is there any sound reason for choosing a display color (grey) which always needs ALL subpixels illuminated, thus causing three times the battery drain a red, green or blue display would cause ?
Do I overlook something ?

AMOLED display is just multiple lights producing images. The reason the ultra power saving mode is black and white is because AMOLED display will turn off the light in the subpixels to produce the black color.

U r right ...
So... Instead of white pixel there should be one of 3 main colors ( red blue green ) in order to minimize the power consumption .
Using white pixel makes no sense for AMOLED displays ...

does having a red blue or green tinted display make any sense to you ? that is why.

Found this information, maybe it is useful:
An AMOLED doesn't have a backlight at all.
Instead, each little sub-pixel is like a tiny red, blue, or green colored light.
If the screen is instructed to display black, it doesn't need to block any light, it simply doesn't light up any of the little colored sub-pixels.
So theoretically, black pixels save you a lot of power because those pixels can be turned completely off.
However, people sometimes make the mistake of thinking this is a function of brightness—that dark colors like gray are similarly efficient.

Did you understand the purpose of an energy saving feature ? - I'll tell you. It's for saving energy.
Not for giving you a pretty sight.
Basic information (I thought everybody knew that): AMOLED indeed is like millions of single LEDs. The more illuminate, the more power you need.
Black screen: NO energy consumption. White screen: Highest energy consumption (because white light consists of red, green and blue light). Red, blue or green screen: 1/3 energy consumption, because just one out of each three subpixel LEDs is lit, thus just one out of three subpixel LEDs consumes energy.
So you need ONE LED for displaying a red, blue or green pixel. But you need THREE LEDs for displaying a white or grey pixel, so it's three times the power consumption.
Now again: It's an energy saving feature. With a green, red or blue screen, energy consumption would be 33 %. But with a grey screen, energy consumption is 100 %.
So where's the sense ?

you're incorrectly making the assumption that an active subpixel always draws full power.
if a subpixel is used to display #808080(which should be a very average grey) it should use around 50% of what it uses when used for displaying #FFFFFF(white)
I don't know how power consumption scales compared to brightness, but using multiple subpixels at 25-40% instead of 1 subpixel at 100% would save a lot of power if power consumption scales with an upward curve as brightness increases.
I don't know the exact characteristics of OLEDs or the effect that pentile has on battery usage so I can't exactly tell why it would drain less in B&W than in color, but grey definitely drains less power than white.
1 interesting thing I just found out:
while I've had several OLED devices, the Note 4 is actually the only one I've ever seen that turns off subpixels to display pure black(#000000)
other devices keep subpixels at their lowest active setting, resulting in a faint green/grey glow.(effectively #010101-#101010, as the lowest setting can vary in brightness between different subpixels)
a downside to this is that black causes ghosting, as it takes a subpixel significantly more time to wake up than to increase brightness.
EDIT: I just did some calculations and comparisons, although this example specifically applies to RGB screens you'd notice a similar effect in RGBG screens.
to create the B&W equivalent of a single colored subpixel at 100% brightness you'd need 3 subpixels to be at only 28%.
even if power consumption is linear to brightness it would still mean a drop in display power consumption of 16%

no its for pretending to save energy not to actually save it. it looks like its an eink screen in that mode so people are happy. thats the sense.

Possibly another reason for choosing black and white instead black and green or other colors to have subpixels "age" at similar rate instead one color loosing brightness at faster rate than others.

Nexus 6 LED can show 7 colours

I was wondering which colours the Nexus 6 LED can show. I've always used LEDs and loved the different blinking modes available in Lightflow. However, the Nexus 6 doesn't support it (except doing it manually which keeps the CPU alive all the time). So I needed to use more colours to know which notification I'm getting.
I ended up doing this image in order to show you guys what the Nexus 6 LED is capable of. It's not every colour, but with 3 LEDs (red, green and blue) you have at least 7 combinations. I've tested all the presets in Lightflow. Maybe there are more colours, but whatever colour I've chosen it's one out of these 7 (using #000 or black doesn't activate the LED at all fyi).
There are:
- Red
- Orange/Green
- Green
- Orange/Light Blue
- Light Blue
- Blue
- Pink/Blue

Yeah, well the thing with the nexus 6 led setup, is that there really isn't much in the way of intensity control, and there really are just 4 distinct LEDs (red, green, blue, and green... yes, two greens.) on it, rather than having a multi-led with a proper fuzzy/dispersal cover over them to blend them together.
