Yesterday at the AccessibleWeb@U meeting (a monthly event at the University 
of Washington) Matt McMahon,Senior Fellow in the Department of Biological 
Structure presented "Web Design for Color Blind Users."  Notes from that 
meeting are available at: 
(Scribe =  Rick Ells).

A "Set of colors that is unambiguous both to colorblinds and 
non-colorblinds" is referenced [1].  Where the Brewer Palette is a palette 
of acceptable color combinations, this palette identifies colors that they 
claim are "unambiguous both to colorblinds and non-colorblinds."  Further, 
they recommend
"When combining colors from this pallet,
- Use 'warm' and 'cool' colors alternatively.
- When using two warm colors or two cool colors, put distinct differences 
in brightness or saturation.
- Avoid combination of colors with low saturation or low brightness."

I would like to see a comparison of this palette to the Brewer Palette, if 
someone is willing to make the comparison.
