Mid-key values give Cubism its characteristic quietness - nothing blazes, nothing disappears. Cool tones set the register here - the blues and greens easily outweigh any warm accents. All colours lean toward grey, building depth through value rather than colour punch. #C4A15D delivers the chromatic peak at only 4.2% - a small shot of colour with outsized visual impact. The full value range is 55 units: broad enough to build convincing three-dimensional form. The palette has the character of outdoor light: cool, mid-bright, with colour rendered faithfully rather than expressively.
