What would be the ideal color for drafting rooms or any rooms used by art students?
Really, the ideal color is one that makes the students most comfortable and therefore able to focus on their work. However, that answer is likely to vary significantly from person to person. From a color science and perception perspective the best color would be a neutral gray and generally a light gray is preferable. The reason for this is that the gray will not bias color perception for any other colors being viewed or used in the artwork. This is why standard color viewing booths have a light gray interior. However, making a room completely gray might be a little too drab and cause students to not enjoy being in the room. So a little bit of color in the room is probably helpful. It’s probably best to just avoid an overall bias toward a single highly chromatic hue.
