Possibly the largest complaint I have with the Galaxy S2 is the screen color balance.
Im guessing they did this for the wow pop factor that is so common when you're shopping for TVs. Yeah, looks cool when you first see it, but after a while, its bugs you. Well, it bugs me. The AMOLED screen has insane contrast ratio.
So after some mucking about, I got the color balance the best I could get on my phone while still keeping the contrast ratio the same. I avoided filter apps such as Screen Adjuster. Its not perfectly balanced, but Its Waaaay better from how it is stock. My settings may not work for you, but will give you a starting point to tune yourself.
------------------------------------------------------------
Requirements:
1. Touchwiz Rom or AOSP like CM10.1/CM10.2 (Pretty much any ROM will work I think. I did this on CM10.1)
2. Dorimanx Kernel (Important, will allow you to do some fine tuning) http://forum.xda-developers.com/showthread.php?t=1617219
3. STweaks. This is to access the kernel features. On the latest kernel 9.37, this app wasnt included in the kernel. You can find it in the play store here: https://play.google.com/store/apps/details?id=com.gokhanmoral.stweaks.app&hl=en
-----------------------------------------------------------
How to: CM10.1/ CM10.2 (AOSP)
1. Go to "Settings"
2. Click "Advanced"
3. Go to "Screen" tab
4. Click on 'Mode"
5. Set the mDNIe Mode to "Natural"
6. Now open the "STweaks" app
7. Go to "Screen" tab
8. Uncheck "LCD REDUCE POWER"
8. Set "Blue Color scale" to 132
9. Set "Red Color scale" to 132
10. Restart Phone
11. Profit?
---------------------------------------------------------------
How to: Touchwiz
1. Go to "Settings"
2. Go to "Display"
3. Change the mDNIe Mode to "Natural". I don't know exactly how to get there; I haven't used a touchwiz ROM for over a year... I forgot. But its under Display... somewhere lol (if anyone can tell me how to get there, ill update the post)
4. Now open the "STweaks" app
5. Go to "Screen" tab
6. Uncheck "LCD REDUCE POWER"
7. Set "Blue Color scale" to 132
8. Set "Red Color scale" to 132
9. Check "mDNIe Sharpness Tweaks"
10. Restart Phone
11. Done.
----------------------------------------------------------------------------------
Now the screen settings may not be perfect for everyone. But you can tune it using the color scale. The goal is to make the grays too look actually gray. Tune it so there is no shade of yellow, blue, green or red.
I tried to match the gray present in the Messaging app on CM10.1. Worked for me.
All credits go to the Devs who made this possible.
Will this work on Apollo Kernel 4.9? stweaks descriptions says it's for siyah kernel only? I'm running Neatrom lite.
EDIT:
Using the Screen Adjuster filter, install button on application installation panel doesn't work. Hence not recommended.
I use check. Lcd reduce, and set blue to 123 in stweaks.
Screen set to standard. Natural look awful

I havent tried that kernel. STweak works with any SII kernel that allows you to make some kernel tweaks. Its a frontend app.

For those not geeky, staying away from rooting may try an app on playstore SCREEN ADJUSTER apk. Worth trying though the adjustments required in my case were very minimal, increased marginally blue, red, reduce brightness a bit and lower contrast.

I mentioned screen adjuster in my OP. Although it allows you do tune color somewhat, the major downside is that it decreases contrast and lights up black pixels. this can decrease battery life. But I agree, If you are staying away from Kernels, than it works okay.

Nice. I Tuned the screen as close I can get to my Nexus 7 (2013). The i9100's screen is way supersaturated. But, I understand, to each their own
So, settings from first post is tuned to look like an nexus 7. Colors seems to pale forme then !!? I will try to set my s2 according to my Optimus g.

Good post, but one problem with this is that although it fixes the greyscale, the whites still look awful at anything other than full brightness perhaps. There is still way too much green, and I suspect Samsung made it that way due to OLED degradation issues with the S2 having a RGB pixel layout.I managed to fix the whites by modifying the excellent Galactic Night app made by arpruss, however I had some SOD issues that I suspected had to do with the app so I gave up on it.
If someone is interested I've developed an App called "ColorModeChanger" to change saturation and color mode of AMOLED screens. You can visit this XDA thread: http://forum.xda-developers.com/showthread.php?t=3154845
Here is my settings.. RR 5.5.2 rom. This setting is for cm12 based ROMs and looks great.

Is there a way to adjust the color temperature of the screen to a more natural white? I have tried the few screen modes in the settings but the Cinema one is still not very natural to me.
Is there an xposed framework mod or Rom that can do this?
Thanks.
I'm looking for it too. Tried some screen adjusters apps but the result wasn't really good as they just apply a filter layer above. I was used to my Note 2 color temperature wich is pretty higher than the 6500k reference resulting in a colder white. The Note 4 display in fact is more acurate, but I found it too warm for me. Whites seem a little pink to my taste. Wish I could raise the value, but I guess we must wait for a custom kernel with this capability.
One quick tip that might help.
Go into accessibility visual settings. Do the thing with the color adjustment and intentionally get them wrong. then move the slider almost all the way to the left.
You will no longer get to modify the adapt dispaly photo mode settings... but it will give a color temp somewhere in between.
you can alwyas set a triple click to shortcut to accessibility to disable it.
Oh thanks! Still not perfect but quite better this way. And without need of dirty kernel tricks.
I think the note 4 screen is too warm.
Is there any solution to make it cooler?

Hi
So let's take a break from pursuing after Lollipop and improve what we have
Well, many of us know that a report came out suggesting that 'blue light' emitting from screens of mobile phones, TVs, PCs etc is harmful to the eye and causes sleeping problems.
And then many apps started coming out which remove/filter the blue light from phone screens, such as Bluelight Filter, Dark Screen, Twilight etc.
These apps do what they say but :-
1) They don't do it perfectly
2) You have to manually disable them each time you install something or grant superuser access to an app
3) Few of them consume fair amount of battery
4) And some people may be annoyed by the fact that it always stays on the notification bar.
So here's another the way of removing the blue light without causing any of the above mentioned problems
The way is to change the kernel settings, rather the screen color settings by using kernel tweaking apps like Faux123, Trickster Mod etc which almost every custom kernel user has.
So open your kernel tweaking app and go to' Screen' settings or 'Screen Color' settings or whatever is there and just reduce the quantity of the blue color according to your preference
I have attached a screenshot of blue light being reduced using Trickster Mod app.
Don't forget to hit thanks if this helps
Thanks for the tip,
I've seen someone using bluelight filter app with his z3 compact, i couldn't figure why. Now i know. The screen of his phone looked pinky though.

Which version of trickster mod did you use, i do not see anything related to screen settings in the version i have
Yellowish color screen after flashing arymod 4.0 or Flex_Lollipop Rev2.1, also tried 3 different kernels: LP_Xplorer_Rev1.7, darkqueen latest and perseo matergold. Still can´t get rid of this yellowish tint when the screen gets dimmer.
A photo would be good, I guess?
So you have only two options, either flash Stock ROM and have the display as it was, or you can use the app Screen Adjuster and turn up the Blue channel to neutralize the Yellowish effect. Remember, with that app you will just be masking the tint, not get rid of it, well not fundamentally.

Thanks for the help, I've also tried that app but the problem is if I neutralize at lower dim when brightness goes up the colors are messed up again. I´ll post screenshot.
I was going to post screenshot but it doesn´t show the problem and I don't have a secundary camera to take a photo.
xinfinityoO said to try and use synapse "Tip for the people with yellowish color hue
Go to synapse / screen and enable mdnie control , there you change the "Digital edge enhancement", try every sharpness value."
But color still messed up
Oh okay. Then you will have to ditch either the ROM or the kernel, I can't be sure which one is causing that (or maybe this is intentional), look for which one says stuffs about display tweaking, should be mentioned under the details of either the ROM or the kernel.
And screenshot won't capture that actually, a photo is needed, from a camera. Screenshots from all the Note 3 of the world will look all same.

I thought there was way to upload a synapse profile or something that could neutralize this. Everything works like a charm and at high brightness there is no yellowish issue only when it's dimmer.
Oh Synapse, no idea mate, have stopped using that buggy piece of software a long time ago (no offence).

It was actually my first time using it and only to try and solve this issue but did find it quite unstable.
What is "Yellow Tint Display Problem"?
It shows us leds are slowly burning inside and this problem is not sgs2 only. All samsung phones (maybe other brands too but I'm not sure) which have LED screen have this issue after some usage.
Our device is 4 yo and I think your white color is yellow and other colors are washed, like my phone. If you look closely your status bar on full white screen you will see clock signal and battery bar's shadow is there. And this is perfectly normal.
SOLUTION
USE A KERNEL WHICH SUPPORTS COLOR CHANGING.
I am using Gustavo's kernel and I edited colors. Now my whites look like more white and all colors look good. I don't have a camera to show you the difference (screenshots are don't prove it). After flashing a color changing supported kernel download synapse.
I am not responsible to anyhing if anything happens on your device.... bla bla bla usual stuff.
So here is my settings. Try and see the difference!
Dynamic Colors:
1. Make sure Scenario and Mode is Default on Screen section then swype to Colors
2. MDNIE Hijack -> CHECK
3. Red Level -> 220
4. Green Level -> 220
5. Blue Level ->6
220 for 3rd and 4th step. Because 255 is not look like natural (looks gross)
Blue level is 6 because of balancing yellow and blue to get a perfect white
DO NOT TOUCH A SETTING from Red-Green level to Cyan-Red level
6. Cyan-Green level -> 220
This setting for more blue. Blue looks like purple on my screen. Now FIXED
DO NOT TOUCH A SETTING from Cyan-Blue level to Magenta- Blue level
7. Yellow - Red level -> 240
8. Yellow - Green level -> 240
9. SKIP
10. White - Red level -> 240
11. White - Green level -> 240
This settings corrects white screen
More Natural Look (I personally using this)
1. Make sure Scenario and Mode is Default on Screen section then swype to Colors
2. MDNIE Hijack -> CHECK
3. Red Level -> 220
4. Green Level -> 220
5. Blue Level ->6
6. Red-Green level -> 30
7. Red-Blue level -> 30
8. Green-Red level -> 50
9. Cyan-Red level -> 50
10. Cyan-Green level -> 220
11. Yellow - Red level -> 240
12. Yellow - Green level -> 240
13. White - Red level -> 240
14. White - Green level -> 240

Many thanks! A great noticable difference., I use your natural settings.
Sorry but how can I access to those settings? I'm on CM12 and flashed Gustavo Kernel for CM12, installed stweaks. But I cant find such settings in stweaks or in general system settings.

These settings are tested on cm11 gustavo kernel on synapse not cm12 stweaks. I don't know if gustavo's cm12 kernel supports color changing. Try on synapse too
Thanks so much dude.

Any recommended settings for getting punchy and vibrant, non-oversaturated colors? I like my screen a bit dark and then compensating the lack of overall brightness with using some more screen brightness instead - the best of two worlds?

a non-oversaturated screen + dark overall colors + making the screen more bright is a really hard combination to figure out!
but i tried 2 different settings that maybe fits your recommendation.
as i tried different setting that combines all your requests, i got that we cant have a dark screen with a good brightness in a good case.
======================
Setting #1 : Punchy Dark N.O.S.
White Balance:
Red:64
Green:64
Blue:85
Color Control:
Saturation:50-60 (as you prefer)
Value:120
Contrast:145
======================
Setting #2 : N.O.S + Bright Screen
White Balance:
Red:0
Green:0
Blue:40
Color Control:
Saturation:55
value:135
Contrast:142
======================
Note1: the first setting is better in my opinion because it has a better viewing angles
Note2: Set the white balance after the color control(because after setting color control,the white balance restores somehow!! )
Note3: You can set the saturation as you like in both setting but i prefer these
