Simultaneous contrast is not just a curious optical phenomenon - it is the very heart of painting.

Repeated similar experiments with adjacent colors will show that any ground subtracts its own hue from colors which it carries and therefore influences.

I prefer to see with closed eyes.

Ah, the creative process is the same secret in science as it is in art. They are all the same absolutely.

In order to use color effectively it is necessary to recognize that color deceives continually.

Easy-to know that diamonds-are precious, Good-to learn that rubies-have depth, But more-to see that pebbles-are miraculous.
