M.C. Escher works in the upper reaches of the value scale, creating an atmosphere of brightness and expansiveness. M.C. Escher tilts toward cool - blues and silver-greys carry the structural weight. Chroma is kept low across all colours, producing the soft, enveloping quality that characterises tonal painting. #663B30 functions as the palette's exclamation mark: highest chroma, lowest percentage (2.6%). A value spread of 57 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. High luminosity and cool temperature suggest the plein-air condition: unfiltered daylight and open sky. This is palette 1 of M.C. Escher's sequence - a single chapter in a chromatic story told across many works.
