Luminism keeps values measured and balanced, a hallmark of tonal restraint. Built on cool foundations: the palette favours the blue-cyan-green arc. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. The saturated accent, #988143, registers at 2.9% - sparse enough to feel like a deliberate surprise. From deepest dark to palest light, the palette traverses 68 units of the value scale - a span that creates natural depth. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source.
