Set temperature based on camera input

[rhendric]

I found this project while looking for a way to set my monitor's color temperature based on the ambient light in the room, but it seems—unless I missed something—that this sets brightness based on camera input but only sets color temperature based on location and time of day.

Before I go diving into how to write a module or a patch that does this, is this something that I'm likely to be able to implement? Any pointers? Or should I keep looking?

Hi! Thanks for opening this issue! Clight offers such an option under "ambient_gamma" config key: https://github.com/FedeDP/Clight/blob/a4d4762ce6f9ff84e2c843939c9171ac72e2a41d/Extra/config/modules.conf.d/gamma.conf#L42 It should satisfy your needs ;)

Ah, not quite, but it's my fault for being imprecise!

It looks like ambient_gamma sets the temperature of the screen based on brightness from the camera, but not color. I'm looking for a way to set the temperature of the screen based on the measured color temperature of a white object that the camera is pointing at, so that the white point of my monitor matches a white sheet of paper on my desk, without assuming that bright light is blue and dim light is red-yellow.
