This is an update (version 1.2), not a new package, but given recent 
postings on the R lists an announcement may be helpful.

The 'dichromat' package has color schemes designed for people with 
red-green deficient or anomalous vision, tools for simulating the effect 
of color blindness, and tools for creating color ramps and palettes (these 
last will be in R 2.1.0).

I would welcome feedback on the accuracy of the simulations of color 
blindness from people who are actually affected. They are based on 
published algorithms and methods, but color matching is always tricky.
