I love color. One of my favorite college courses was a class on color theory where I learned that color was a lively thing, capable of surprise and even deceit. I enjoyed this article on The Meaning of Color today. I also want to recall this nice color theory tutorial.
The course was taught by Richard Lytle and was, I think, largely based on the plan set out by Josef Albers in his book Interaction of Color. I wish more art departments had such welcoming courses, so many jump right into drawing and never look back.
