one may hide behind the $ (shortened because screen wasn't wide enough...)

Code:
Neutral=0;330;0;160;28;28;8;195;38;8;8;250;330;9900;0;160;28;28;8;195;38;8;8;250
Vivid=0;33000;0;205;0;0;0;245;0;0;0;265;33000;-1;0;235;-10;-10;-10;265;-10;-10;-10;285;33000;-1;1;255;-20;-20$
Muted=0;-1;0;115;48;48;15;152;73;32;32;200
i'm sure there are 4 sets

That's ok but I asked because many coefficients other than the initial ones of RGB colors are different from what I have with me.

i.e. not only Red but Green and Blue value are also changed. So I needed those for this purpose.

Np

Code:
[Display-c1]

# Color phase adjustments for the c1.* display revision
# Each value consists of sets of 12 numbers, each forming a entry for certain
# brightness range, the sets contain, brightness values in lux*3.3
# (330 = 100 lux):
#  - brightness range lower limit (one of the ranges should start from 0)
#  - brightness range upper limit (one of the ranges should have -1 = unlimited)
#  - high brightness mode level
#  - 3 coefficients for output red channel (red, green, blue)
#  - 3 coefficients for output green channel (red, green, blue)
#  - 3 coefficients for output blue channel (red, green, blue)

Neutral=0;330;0;160;48;13;22;195;28;8;8;250;330;9900;0;160;48;13;22;195;28;8;8;250

The two display entries (c1 and fe) in mce.ini correspond to two different display panel versions from two different manufacturers. That is why different N9s may have different color reproduction. You can dig up your panel version information for example from boot log with dmesg and grep:

Code:
dmesg | grep -i pyrenees
("Pyrenees" is the code name of N9 display panel, regardless of the manufacturer, I guess.)

Here is my outcome:

Code:
[    0.307434] panel-nokia-dsi display0: pyrenees panel revision c1.8b.96
[   11.115112] atmel_mxt 2-004b: firmware: requesting RM-696_Pyrenees_LGD_V1_1.bin
Panel revisions (and my observations):
  • "c1" (by LGD, LG Display)
    • reddish tint sometimes
    • more visible pixel matrix
  • "fe" (by SMD, Samsung Mobile Display)
    • greenish tint from extreme viewing angles
    • less visible pixel matrix

-3 values for the green color channel (R;G;B)
-3 values for the blue color channel (R;G;B)

...

e.g
Neutral=0;330;0;175;48;13;22;206;28;8;8;240;330;9900;0;175;48;13;22;206;28;8;8;240
The brightness values are the ambient brightness levels, measured by the ambient light sensor, not the display brightness! Unfortunately, I don't know either what that high brightness mode is, so there is still something to figure out. Maybe that is related to the selected display brightness level?

So you can define different color tunings for different lightning conditions inside one color profile (for day, night, etc.).

For example in that Neutral color profile, there are different color tunings for ambient lighting range 0-333 (i.e. 0-100 lux) and 333-9900 (i.e. 100-3000 lux), respectively. You can add more ranges, if needed. (Actually Neutral profile is not fully defined, as the range from 9900-(-1) (i.e. from 3000 lux to infinite) is not covered!)

Color profiles can be changed easily from command line as the setting is a GConf value, so you can do it with Profilematic.

Here is discussion how to do it:

Consider also trying to use ambient brightness ranges of the color profiles themselves, if you want different color tuning for night etc. (See my previous post.)

How to bring up the boot log?

Edit: Typed command: dmesg | grep -i pyrenees

nothing happened in the beginning.

Then Kallela advised to reboot the phone. Entered the command
again and the info was there.

Thank you Kallela

Yes, I'm already finishing the app that adds and transforms the phone display to adhere to 3500K blackbody.
Brightness ranges don't really influence this idea. But I'll see and do my best.
