Anyone else find the colors on the P4A washed out? Anyone addressed this using color control/RGB control? Any profiles to share?
Yeah I noticed the same thing after I used my previous phone. I simply upped the saturation and contrast a little and I think it looks better.
Is there any possibility to control saturation / contrast / RGB in the stock ROM and with the stock kernel? Or is it only possible with custom kernel / ROM?

I don't think you can do that without a custom kernel. But if you didn't know yet, under display settings there are a few preset color profiles available you can choose from.

I came to the Charge after a brief stint with the Nexus S 4G. On that device, there was a Voodoo-based kernel available which allowed the user to make adjustments to the color settings of the display. AFAIK, these color modifications are not included in the Voodoo kernel for the charge. Does anyone know whether it is possible to incorporate these in a future kernel and/or whether there is any other method out there to tweak the display?
I looked at incorporating Voodoo Color, but the methods that are modified by the Voodoo Color changes do not exist in our display driver.

Too bad. Thanks for the quick reply though, imnuts.
Hello,
The screen on my smartphone has a very slight problem. Shades of gray are dull and lack contrast. I searched for an app to increase the contrast of the display, but I didn’t have found. I tested several app to modify the brightness or decrease the contrast as "ScreenDim Full" and "Screen Adjuster". But I didn’t find any app to increase the contrast. So I need your help.
What app can increase the contrast (not decrease)?
I think that increasing the gamma may also allow me to have a better display. In an AOSP ROM, in the settings, we can choose between two gamma values: 2.2 or 1.9. What value to modify in which system file to change this gamma value?
Thanks !
The Galaxy S4 has a good screen but it's a little too over-saturated giving unnatural skin tones. Switching to "Movie" mode results in rather muted colors. For accurate color reproduction there's a new app "Calibrated photo Viewer" on Google Play with pre-calibrated color and gamma corrections to show photos in their natural colors.

Adobe RGB and sRGB color spaces are supported so both standard and professional photos can be viewed seamlessly, without the need to switch 'screen modes'.
The app works just like a normal photo viewer. No rooting is required.

Added color balance controls
I have added controls for custom fine tuning of color balance, to allow for variations between different S4 devices.

I'll check it out, thanks! I'd love a way to set the rgb for the whole phone, not iust one app, as my whites are quite greenish in comparison to many other screens-is this possible without kernel modifications?
Unfortunately I don't think that is possible without a mod kernel.
Check out the new version with Auto Color Balance.
Use a camera on an external android device as a color measuring device.
No more fiddling with color controls.
The two devices communicate via Bluetooth.

Requires a free companion app Camera Colorimeter on an external device

It is very good for IPS screen except Hwawie phones
To get the most powerfull color
Select custom & change S value to 1.89

I don't understand, does this actually change the RGB? I thought that was only possible with a custom kernel??

Does anyone know the RGB values for cm13's night mode?
Awesome about to try
Some roms cannot xhange rgb. This apps helps but it trial for the feature. Sad
I know its would be pretty easily acheived through tasker with the current version, but an update to change colour profiles (particularly the daylight oversaturated one) based on ambient light level would be most appreciated.
Great app otherwise! Especially useful for kernels and devices that don't support kcal.
Any change of values results in framerate drop across ui. I'm using Xperia ZL on stock 5.1.1. The stutters in ui are constant until switch it back to normal and reduces the experience greatly. If there was a way to increase saturation without having to deal with those frame drops it would be awesome.
If you can fix it with an update please do it.
The stutters I experience are similar to those when I enable simulate colo space in developer options.
this app is awesome to increase saturation and get more vivid colors
Old issue for me the color management of Idol 3. Stock ROM has ugly vivid colors, so for example I have to use 3rd party gallery instead of stock's, because it distorts colors. That's the case with Chrome as well I just realized that I can't test colors of a website ('under construction'), because it just show me distorted colors.
This problem never existed with CM roms, only with stock.
Do you know any way to disable this terrible color profile?
