Ok, so I have to agree with the others now after using the site for a bit. Its very difficult for me (partially color blind) to read. The links on the gray are almost impossible (I have to highlight posts to read them now). Simply taking the text to pure black with the links to a darker shade of gray would work out in most cases (at least for me).

Since SMF does support multiple themes, maybe install a few so people can pick what one they want, or hold a contest here on the board to design a new look and feel for it.
