Yes, that's what I'm saying. :-)

Well, I do tend to prefer the number 6 values in the Brewer color tables
as plot colors (these are on the right-hand side of cgPickColorName, to
the right of the column of beige colors, "red6", "pbg6", "ygb6" etc.).
These are probably constructed from an HSV color scheme along the lines
you suggest.

Cheers,

David
