Run the provided software demonstrating the relationship between luminance and RGB value. Locate the colour map shown in Fig. 4.13(a) that runs

from sky blue through to orange via equiluminant grey. What is the saturation and value of these endpoint colours? Locate the colour map that runs

orthogonal to this one, linking pale-ish magenta with darkish green. Estimate

the RGB values of the endpoints of this colour map and put them into (4.1)

to confirm that luminance remains constant at one-half.

Construct a colour map linking dark yellow and pale blue that has luminance constant throughout at one-half. This colour map lies on a line halfway

between the two already described. Use this colour map in the software supporting Prob. 4.3 in place of the one provided originally and adjust the grey of

the background as before. What effect do you see and how would you explain

it?
