The color table contamination is occurring because you are calling your
cgPlot command incorrectly. You specify the AXISCOLOR keyword like this:

AXISCOLOR=cgColor('white')

And you should be doing it like this:

AXISCOLOR='white'

The difference is that the way you are doing it, cgColor is forced to
load the white color somewhere in the color table (because you are using
indexed color), but if you allow cgPlot to load the color it will do it
using decomposed color and never have to load a color in the color
table.

Cheers,

David
