About Colours (continued)
HSB Model
This model is based on the human perception of colour. When our eyes perceive
colours in objects, we receive the information not only on the colour itself (reddish,
bluish, etc.) but the brightness (rather bright, dark, etc.) and the purity (vivid, dull,
etc.) of the colour.
The colour perception (reddish, bluish, etc.) is defined as hue (H). The strength or
purity of the colour is defined as saturation (S), and the lightness or darkness of the
colour is defined as brightness (B).
The above three elements are called the three attributes of colour. With these three
attributes, the Munsell colour system has been created to describe colours in a
three-dimensional space.
