Allow adjusting screen color temperature (like f.lux, redshift)
|Reported by:||v-l||Owned by:||nobody|
Haiku lacks the option of changing screen color temperature (https://en.wikipedia.org/wiki/Color_temperature), that is, making the screen redder in the evenings to reduce eye strain.
Implementing this in Haiku (or as a separate program) would make Haiku much more usable for users who work in the evening. I think this could be done by letting users or programs change gamma correction of the screen.
