Has anyone experience being in a room lit with different colours (one at a time).
If so which did you find best or was one good some time and another one at another time?
Are you asking about colour temperatures, or flat out colors?
To be honest, it's hard for me to tell if I'm in a cool white or warm white room if I don't have a reference.
Additionally, I used to work in a call center that had very vibrant wall colors... so one room would seem purple, and once you were used to it.. the lighting felt white again... until you moved to a different room.
If you want to use a specific colored light (red, blue, purple, green, etc. ) Then everyone has their preference.
It makes certain object in the room hard to see properly.. (ie, one or more buttons on a game controller will appear extremely dull, or if the colors line up just right, some colors will apear flat out .. black.
