On Academia.SE, the color of non-visited links is blue, and the color of visited links is red:
However, on every other SE site I have visited, the color of visited and non-visited links are slightly different, but similar. Normally, they are different tones of the same color (which is also the color of the "Ask Question" button). For example, on Artificial Intelligence.SE, non-visited links are purple and visited links are dark purple:
Is the color of the links on Academia.SE an oversight (i.e., should non-visited links also be red to match the color of the site's buttons) or is there a reason for this apparent inconsistency? The first time I saw a few red links between all the the blue links, it did look like there was something wrong with those questions.
