Are there any R functions for creating palettes for three-way data? For example, election maps for three parties where pure red, blue, and green show 100% for the Red, Blue, and Green parties respectively, magenta shows a 50-50 Red-Blue split with 0 for the Greens, cyan a 50-50 Blue/Green split with no Red votes and so on, with grey, black or white at a 1/3,1/3,1/3 split vote.
I've spent a couple of half hours knocking out a function to do various versions of that, including using Red/Yellow/Blue for the primaries with Orange/Green/Purple for the 50/50s. I'm wondering if a) There's existing functionality in one of the packages on CRAN (I've had a look and googled) b) Anyone can point me to information about colour perception of this kind of three-way colour scheme. Thanks muchly.
