Perhaps the most simple color limit

Perhaps the most simple color limitation is to use one chroma. We refer to this as a monochromatic palette. This well-known example is by Ingres. Picasso’s Guernica is another famous monochromatic work. The contemporary American artist, Mark Tansey, works just about solely, in monochromes, from blues to greens to oranges and reds. This is really a form of working with value though hue plays its part. A blue painting will feel different, cooler, more icy, and less humid, than a warm gray, much less an orange painting.
