Dear Jeff,

Some time ago, Don McQueen posted to r-help a nice function for displaying
the named colours. You'll find it at
<http://finzi.psych.upenn.edu/R/Rhelp02a/archive/31607.html>. As well, if
you're using R for Windows, the various named colours are defined in the
file rgb.txt in R's etc directory. 

I hope this helps,
