Luca Signorelli keeps values measured and balanced, a hallmark of tonal restraint. Heat pervades this palette; warm chromatic identities outweigh cool ones at almost every weight. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. Only 4.6% is devoted to #943F23, yet that small allocation delivers the palette's entire chromatic tension. From deepest dark to palest light, the palette traverses 63 units of the value scale - a span that creates natural depth. This is the light Luca Signorelli preferred, made measurable.
