Figure 2.17
Highly simplifi ed three-dimensional representation of Munsell colours. (a) The axes for value, hue
and chroma within a sphere. The 10 hues are shown but for simplicity the 10 subdivisions within each hue are
not shown and neither is the chroma. (b) Sphere of colour with the colours becoming lighter towards the top
(increase in value). (c) Part of one segment showing very generally the increase in value towards the top and the
increase in chroma towards the outer edge of the segment. (d) Part of a Munsell colour chart specially designed
for rocks. In this case the grey organic-rich mudstone sample on the left has a Munsell colour of 5Y 2/1 (olive
black).
