Suggest: support color management

[tabit]

In the current version, since the game ignores the color profile, the contents of the game will be excessively vividly displayed on wide-gamut displays. 

For instance, the buttons in the lower left corner will be dazzlingly red, and so do the red bubbles that remind the pipes and cables are unconnected.

I hope the game could support color management, such as assigning a sRGB color profile, so that the wide-gamut displays can display the color correctly.
