The light in the room where we draw is lit with low pressure sodium lights, which are great for energy efficiency, but terrible for colour rendering accuracy. Under those lights, I lose all perception of the red spectrum, which isn't a problem when I'm drawing, but is a definite challenge when painting. I always emerge from the room with a far more highly saturated painting than what I'd perceived. Last night I paid closer attention to my colour mixes and tried to get the tones right, so the painting isn't quite as far off as usual. Still, it's a little like painting while colour blind. I love the Cambridge life sessions, so maybe I'll look into getting some kind of clip-on light with high colour rendering index to take with me on painting nights.
