A small free tool for OS X I found useful is Sim Daltonism[1]
Sim Daltonism is a color blindness simulator for Mac OS X. It filters in real-time the area around the mouse pointer and displays the result ” as seen by a color blind person ” in a floating palette.
If anybody has information about how people with limited color vision perceive the aesthetical side of colors (e.g. how well colors go together in a web site palette) I would love to read about it.
Also, thanks to this, I've noticed that the common purple color for visited links is distinguishable from the blue it usually accompanies (e.g. Google) for people with deuteranopia.
