Color is integral to many artworks and can affect mood, form and perception. The primary colors are red, yellow and blue. Secondary colors, which are made by combining primary colors, are green, purple and orange. In this video, you discover the Color Field painters from the '50s and '60s who treated color as their main subject.
Red, of course, is the color of the interior of our bodies. In a way it's inside out, red.
