As someone with a bit of a background in ergonomics, I can tell you that some of that 10% of the population are not even aware that they are color blind. If your colour scheme is not "mission-critical" ( you don't rely on colour as a major site navigation tool) then I say don't bother changing it. Note: I did not take a look at the design. I'm offline currently. Nicole ----- Original Message ----- From: "Ron Jourard" <ronjourard at home.com> > I'm redesigning and thinking of using a nav bar with different shades > of green.
