Ed Piskor sez, "I located an 'antique'
chart of the exact mixtures for the 64 colors which were used in
comics and newspaper strips for decades and I created a PSD file to
share so that people can use these hues digitally. It's sort of a tool
that also will remind guys to practice some restraint when doing their
own work. I can't think of a reason anyone would need to use thousands
of colors on a page, but a lot of colorists insist on it. Forward this
to your illustrator friends."
