Wondering what K means in f.lux
I noticed that all of f.lux's settings are some number followed by k (like 4900k). If you don't see this, open f.lux preferences and use the slider. Could someone please clarify what unit "k" is?
Kelvin. It's a unit of measurement for temperature. For f.lux, it refers to the color temperature. Lower Kelvin values are "warmer" because they have less blue.
