Value Scale
Each column shows a palette colour across 7 value levels. The ring marks its natural value. The curve shows the palette's tonal range. natural value · curve = tonal range · row 1 = lightest · row 7 = darkest
Green test — Yellow mixed with Blue
Subtractive mixing should produce a believable green at the midpoint. Yellow

Paint-like mixing
Controls how physically realistic colour mixing is, on a scale from perceptual blending to pigment simulation.
0% — OKLab blend: Colours mix through a perceptually uniform colour space. Transitions are smooth and even, but yellow + blue gives a muddy neutral — not green.
100% — Mixbox (Kubelka–Munk): Simulates real pigment behaviour. Yellow + blue gives green, red + blue gives violet — matching physical paint.
Default 85% blends both modes: paint-like hue results with smooth tonal transitions across the value table.
