Mid-key values give M.C. Escher its characteristic quietness - nothing blazes, nothing disappears. Neither warm nor cool has the upper hand here; the equilibrium between the two generates the palette's visual energy. Chroma hovers near zero; colour declares itself through subtle shifts in hue rather than outright saturation. At 7.6%, #23180B carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. A value spread of 74 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light. In the context of M.C. Escher's full range of palettes, group 2 represents one movement in an ongoing chromatic dialogue.
