I'm working with Windows 7 and I did a big mistake. I installed redshift gui and when this program starts colors became awful. Then uninstalled this program but now I am still looking these bad colors. When I installed this software my monitor is set to 9500K. But Redshift doesn't supports color temps higher than 7000K. When I select 6500k it looks like 6500k, when I select srgb it looks like srgb but 9500k option not work. What I must do? Redhsift changes something in Windows(with command prompt I think) but what is it? It's not the graphic card's control panel or Windows display calibration settings but what?
