Being color blinded is not very easy. You end up wearing black shirts and blue jeans, because it's easier. When you look at a computer monitor sometimes the red and green mix together, all sort of pale colors (from aqua, pale grays such as off-white, and so on) mix together, and many more problems.
Right now it is impossible for me to see if there is a link in the text. I have to guess my way with the mouse and see if something underlines as I hover it. I don't know whether or not the color scheme gives the same color to links, or just a very slight shade, but it's very difficult to discern these things.
This is even worse because the previous version of the site had a clear distinction between the links, the visited links, and the text. So it's not only confusing it's actually stressful.
In addition to the previously remarked "favorite tags" background color, is it possible to make the links colored in a slightly more discernible color? I'd love to be able and distinguish links from text again.
