Hey Guys, I've seen people's color settings all over for the Galaxy Nexus, we have different tools, different kernels and different ways to improve the Purple/Red/Tint Issues with Franco's App, Morfics, as well as free tools like Trickster Mod's App and the new CM10 Color Multiplier, Color Gamma Tuning, and Color Hack presets.

Goal: Have all this information in one place

I have created a Publicly Accessible Spreadsheet on Google Docs that you can edit without sign-in, please either
A:Edit the doc with your color settings or
B: Reply to this thread with your color settings for each different kernel and app and one of us in the thread may update the spreadsheet.
Also only reply if you can provide useful information regarding these issues.

I know allot of people are stuck with their Galaxy Nexus, so lets all work together on sharing our settings and tips/tricks regarding this since samsung still has not fixed the issue and still sends out devices with this issue. I've heard people go through 5-6 replacements, ouch.

Checkout the format of the spreadsheet, and feel free to improve it.

Edit: If requested, I could make a Google Docs form to auto populate the spreadsheet

Anyone know of a way to disable the screen dimming on the notification drop down? When it dims on low brightness the notification and background is purple.

No clue how to get rid of the screen dimming on drop down. You should watch out when running the higher contrast numbers, burn in is a spooky thing. I'm glad that a list of some type is being made (suggestion gathering has been abysmal), although every screen has it's own inherent faults and oddities, it will be very interesting to see the results. Thanks man.

Thanks for this list. I've been messing around with color settings for awhile now with no success. I always felt like the screen had a tinge of green that I couldn't get rid of.

Adding some red should help that. My problem is that there are a couple "hot spots" of yellowing and magenta that I have to strike a balance between. Went through a few different settings but posted my current to the spreadsheet.

Previous:

200,215,280
-2,0,15
-23

And I added a Gradient Fix column since I find using that mod changes what you need for color settings to make things nice.
Also worth mentioning that in some apps the OMAP Gamma runs on a 1.0-2.0 scale (by 0.2s) and in others 5-10 (by 1s), these are equivalent however.

Just wondering, isn't every screen at least slightly different? I'm pretty sure that's why there's color calibration, or the screens would come calibrated perfectly.

There isn't a HUGE variation in the differences. Each screen isn't a special snowflake. There's a relatively small, finite number of different screen settings that work for all screens.

This will give people a narrowed-down list to try first instead of spending hours experimenting.

Im finding my self having OCD in getting this perfect lol, just added another setting that I found pretty nice but there is still slight purple at 1-5percent brightness. Thanks guys for adding your settings to the spreadsheet, I think with enough data we can average the setting variables and find a good base setting

For me color is only an issue below 20 percent and sometimes lower depending on gamma settings, im finding that gamma and contrast seem to help more than the actual color multipliers

Edit: Just updated the spreadsheet with more settings others have shared on XDA, credits go to isinisterx, amit_sen
ÜBER™, for sharing their settings in other threads

Really, the only purpose to document all these settings is for statistics. To show that more Nexus screens come with x-color tint than y-color. Even then, you're trusting people to know what white and gray are supposed to look like. I've seen how most people set up their TVs - they're usually wrong.

It doesn't take hours, it's a pretty easy process:

Color multiplier is white balance, which also affects overall color tone. Get two things: a blank white screen, and a pure black screen with white text (settings is easy if you have gradient disabled.) Use these, and go with what you think white should be, unless you have a good reference or a calibration tool. For example, I dropped red/green because my screen was too yellow stock. I then found that I could still almost see the individual red pixels sticking out of text (best way I can describe it), and looking at my home screen felt a little too "pink", dropped red a little more until it looked fine.

Next is gamma/offset/whatever which is the adjustment of everything in between white and black. This one can be trickier because grays can easily look too red/brown, too blue, too yellow, etc. and on these screens the gray balance will change depending on brightness. Yes, sometimes drastically (see: purple tint) This can be a pain if you need to lower greens because green can't be lowered (the screen goes nuts), and the colors don't scale the same, so if you increase red and blue by the same amount one will probably be stronger than the other.

Just from my experiences. And yes, each screen is a special snowflake. Most people are just happy enough with canned settings.
