Cubism occupies the comfortable middle of the value scale, avoiding both extremes to hold the eye in a sustained middle grey. The dominant temperature is warm, with earth tones and fire-hues setting the emotional key. A restrained, mid-chroma palette: every hue is present and legible, but nothing shouts. #EBC77B is not a small accent - at 4.5% it qualifies as a major presence and gives the palette its chromatic identity. A value spread of 62 units gives the palette both depth and air - shadows are genuinely dark, lights genuinely light.
