Download ADesigner from IBM (its free) (check out my blog, I have the link
there).  It simulates more than just color blindness.

Depends on the person.  Some fail to see reds, some greens, some
blues, some all of the above.  The only thing that's guarenteed to be
totally safe is black on white.  Of course, you can certainly mix
whatever colors you want, just make sure that the colors aren't
communicating information that can't be found in other ways, because
there's not way to be sure that people will see them.

A better way to look at it is in terms of greyscale contrast.  If you
can take a greyscale screenshot of the site, reduce it to 4-8 greys
and it's still usable, you should be safe.

cheers,

If you have Photoshop: Download VisiCheck and test your colors.
