Mid-key values give M.C. Escher its characteristic quietness - nothing blazes, nothing disappears. The palette achieves thermal balance - reds and blues, ochres and greens, each holding the other in check. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. The most saturated colour, #3E0A24, is reserved to 10.0% of the surface, where it acts as a focal punctuation. From deepest dark to palest light, the palette traverses 68 units of the value scale - a span that creates natural depth. The palette is recognisably M.C. Escher's own: particular in its temperature, chroma, and the economy of its brightest note.
