Re: Custom line colors

[Ansley Manke <ansley.b.manke@xxxxxxxx>]

Thank you all for your tests and examples.  It sounds like it's time to
revisit this question and allow for more line colors.  We have an idea
for a means of defining line colors using the colors in a color 
palette.  This
would make it easy to define a lot of colors, and it wouldn't exclude
the existing method of redefining any pen with PPL PEN settings.
