Munsell system

noun phrase · colour theory

Albert Henry Munsell's 1905 three-dimensional colour space organising every colour by hue, value, and chroma. The dominant vocabulary of professional painting instruction in the English-speaking world.

The three dimensions

Hue is the colour name. Munsell uses a 10-step hue circle (5R, 5YR, 5Y, 5GY, 5G, 5BG, 5B, 5PB, 5P, 5RP) with five steps between each name. Value is lightness on a 0–10 scale, where 0 is black and 10 is white. Value is independent of hue — you can compare the value of a red to the value of a green directly. Chroma is saturation, on an open-ended scale. Neutral grey is chroma 0; the most saturated pigments max out around chroma 14–18 depending on hue.

Why painters use it

Munsell's coordinates are measurable. Two painters working from the same Munsell number land on indistinguishable colours; intuition-based colour mixing produces no such convergence. The system was the first to make value independent of hue, which is the single most useful conceptual move in modern colour theory. Most professional ateliers use Munsell terminology in instruction.
