17 Color tables

Figures 17.1, 17.2 and 17.3 show the default named colors which Pyxplot recognises. In addition to using these colors in statements such as

plot 'data' with color red

it is also possible to make custom colors using the rgb(r,g,b), cmyk(c,m,y,k), gray(g) and hsb(h,s,b) functions, whose inputs should be in the range 0–1. For example:

plot 'data' with color rgb(0.8,0.8,0.2)

myColor = cmyk(0.2,0.8,0.8,0.1)
plot 'data' with color myColor

These figures also exclude the 100 shades of gray which Pyxplot recognises, which are named from gray00 (black) to gray99 (almost white). These shades of gray may also be spelt in the UK English form grey??.
