A simple tool for the partially colorblind

I am partially color blind as are almost 10% of all men. I think it would be really cool if when using the color picker (either with the fill or paintbrush tool) I could right cllick on a color within a photo and actually see the numerical color value of the pixel I am on. Since so many of us are atleast partially color blind, I would think this would be a very useful tool not to mention a good selling feature. Thanks fore the teriffic software..
