If you use color to denote information (such as clickability), reinforce it with other methods (for instance, bolding or underlining links). If you've turned off underlining via CSS, consider making links bolder than normal text. If you do this, avoid using bold on nonlinked text, lest you hopelessly confuse the colorblind user as to which bold text is hyperlinked and which bold text is simply bold. [..]

Okay, the first issue seems to be none, since I underline my links, but maybe the link color lacks a little contrast. But the second one - that made me think, so that I've been there and downloaded a plugin for Adobe Photoshop to test how .redSPLASH appears to people suffering from the three kinds of dichromacy.
Although the screenshots are rather tiny, you'll get the idea. If you want to know more about colorblindness, Wikipedia offers help.
