Figure 7.1
A non-linearized grayscale. Black increasing to white, and their gun intensities. The abscissa represents the progression of the colors along the scale.

Figure 7.2
A linearized grayscale.

Figure 7.3
The rainbow scale.

Figure 7.4
The heated-object scale.

Figure 7.5
The magenta scale.

Figure 7.7
The optimal color scale resulting from N = 32, hs = 0, 180 <= he <= 360, and dir = up and interpolation to 256 colors (the RGB gun-intensities and the scale).

Figure 7.8
LOCS: The linearized optimal color scale resulting from N = 32, hs = 0, 180 <= he <= 360, and dir = up and interpolation to 256 colors (the RGB gun-intensities and the scale).
