While on SO, the hyperlinks are light blue and easy to distinguish from simple text, the hyperlinks on Programmers.SE appears visually as much darker, especially for visited links (due to their color).
Not only do I have some pain to make the difference between visited links and text on my home PC, but with some screens in some working conditions, it is completely impossible to find a visited link in a text, and very hard to find non visited links.
Is it possible to make those colors, especially the one used for visited links, lighter?
