BTW, I'm color blind such that nearly all images that I test on the Deuteranope
simulation at Vischeck look identical to the original image. For what its
worth, just about any of the web page attempts so far look fine, and I think
people might be making the color issue more of a usability issue than it
actually is. I don't know if it is even possible to come up with a color scheme
that looks good to both people with normal vision and people with severe
blue-yellow deficiencies at the same time unless the color scheme is grayscale.
>From my point of view, differences in brightness are the most distinguishing
elements, and I tend to prefer grayscale color schemes because there is less
distraction caused by hue. But that's only a preference; it is rarely difficult
(to a significant degree) to navigate web pages or find links. Obviously, there
are people with a much greater degree of color blindness than me, but the
majority (by far) of color blind people don't have significant trouble with
stuff like this.
