Run the provided software2 demonstrating the relationship between the
RGB and HSV colour models. Rotate the solid, coloured cube so that you are
looking down on the white vertex, then turn the solid cube off. You should
be looking into the mouth of a six-sided cone; all the points on this cone represent colours whose saturation is one-half. The square-shaped surface represents colours whose value is one-half. Experiment with the saturation and
value widgets. Where are the fully saturated colours? Where are the full-value
colours?
Use the software to follow the derivation in Sect. 4.3.3 of dark red and pale
green. Derive the RGB equivalents of some more complicated colours such as
dark yellow and pale magenta.
