Munsell Colour System

The Munsell Colour system consists of three independent properties of colour which can be represented cylindrically in three dimensions as an irregular colour solid. The three properties are:

• Hue (basic colour) - measured by degrees around horizontal circles
• Chroma (colour intensity) - measured radially outward from the neutral (gray) vertical areas
• value (lightness) - mesured vertically on the core cylinder from 0 (black) to 10 (white)

It was designed to keep the three properties into perceptually uniform and independent dimensions, and was the first such model.

The drawback with Munsell colour system is that its colours are not specified by a set of equations, but a manually picked lookup table. This can be computationally expensive.
