Most modern monitors (and operating systems for that matter) have functions for day and night colour temperature schemes. I use it a lot since I love reading in bed but don't want to give night blindness to my other half.

If the OS has it, you can set it to gradually phase in and out of the temperature change at a particular time. The Radeon drivers go one step further by understanding that as the year progresses, "night" and "day" happen at different times.
