FAQ

Where did the colors come from?

From the Image::Magick web site. I extracted them from a web page there using the amazing HTML::TreeBuilder module. See scripts/extract.colors.pl.

Why do you discard the first 220 colors?

Because they are too dark for my liking.

Why does the caption use CSS class c0003?

I like that color - it's nice and restful. I seriously considered using c0201.

I want to know which CSS class produces which color.

Patch line 743 to put ' $class_name' just inside the '|' at the end of the line.
