How does light affect color?
The type of artificial lighting in a room will affect the perception of the wall color, and should be considered when making paint choices. Here is a quick guide to the effects of the most popular lighting sources: Sun light is the perfect light source because the human eye has adapted to it over thousands of years. It is characterized by having nearly uniform intensity over the entire spectrum of colors. Incandescent lights cast warm yellow or amber tones that can intensify wall colors. Standard fluorescent fixtures bring out cool tones and green casts. Warm fluorescent, while not as rich as incandescent sources, add warm casts. Halogen lighting is bright and white and distorts color less than any other artificial light source.
