I find it confusing that, on ELL.SE, the links for questions visited are lighter color than those for unvisited questions. This feels backwards to me and I am constantly thinking "I never read that question, but it looks like I've clicked it before...". Can this be changed, and if so, does anyone else have this 'problem' with the current color scheme and want it changed?
The comments above cover the best course(s) of action, but I thought I'd supply some resources for you to cite in your quest.

- The color for unvisited links should be more vivid, bright, and saturated than the color for visited links, which should look "used" (dull and washed out).
- As always, when using color to signal information, you should provide redundant cues for color-blind users. Making unvisited links brighter and more luminous than visited links will usually accomplish this goal.

- Give visited links a darker shade of color, so that they stand out but aren’t as obvious as unvisited links.
It's worth noting that this Meta site uses the usual “lighter = unvisited, darker = visited” convention except for “Hot Network Questions” on the side, which, confusingly, reverses it.
Lastly, for your amusement: this.
