"I disliked colours ground in oil. They seemed dead to me; what pleased me above all were pure pigments, in powder, such as I saw them in the windows of retail paint-sellers. They had brightness and extraordinary, autonomous lives of their own. This was essential colour. Living tangible colourmatter. It was depressing to see such glowing powder, once mixed in a distemper, or whatever medium intended as a fixative, lose its value, tarnish, become dull. One might obtain effects of paste but after drying it wasn't the same; the effective colour magic had vanished." - Yves Klein
