Steps to reproduce the problem:
Chromebook does not offer any way for the user to adjust the color temperature of the display, ie, be able to adjust the RGB value/gain of the display to correct displays that are too blue or too red.

What is the expected behavior?
It would be very useful if Chromebook allows the user to independently adjust the RGB value of the display like computer monitors and TVs. This would allow the user to adjust display color temperature for a better viewing experience and make Chromebook more useful in general.

While be able to apply ICC profiles is certain useful, perhaps more important is the ability to adjust the RGB value/gain of the display independently, like most computer monitors and TVs (through service menu during display calibration process). This simply increase/decrease the strength of the individual RGB color, thereby changing the color temperature as a result. The goal is to reach the industrial standard 6500K, where most film/images are produced for. This will remove any blue/red shift, and allow the display to reproduce color accurately.

Offering this simple ability would allow the user, with the proper tools (color meter), to calibrate the color temperature of the display to 6500K fairly easily. Simply show a white background, read color temperature, and adjust RGB value until all 3 RGB bars reads equal (6500K). The results will be very natural whites with no excessive emphasis in blue/red. Even without dedicated tools, it can be useful to correct displays that have shifted too much to the red/blue, either due to manufacturing issues or age.

Note: I am not asking for a tool that shows a white background (or a sequence of grayscale images). I am simply asking for the ability to adjust the RGB value of the display (while said white image is being displayed), like most computer monitors.

What went wrong?
Without the ability to adjust color, user are stuck with what the default is for the display, which can be very inaccurate. Color will simply look odd/wrong.

Did this work before? N/A 

Chrome version: 57.0.2987.133  Channel: stable
OS Version: 57.0.2987.146
Flash Version: 

Please consider adding this capability. It would greatly increase the usefulness of Chromebook devices and allow it to be used where color accuracy is important.

My ask is not the ability to take ICC profiles, but be able to adjust RGB value directly, which IMHO is much more useful and should be simpler to add.

Thank you.
