>Pictures are very useful when explaining what happens when reducing the total number of colors in an image. Back in high school, there was a dedicated room for teaching psychology, AP psychology etc One of my friends found a book in that room's library that was about color perception. The fascinating part: the book had no color and was entirely in black and white. Even the diagrams they had were black and white line drawings. I always wondered: who sets out to write a purely text book about human color perception?
