New submission from Buck Golemon:

The color needs adjusted such that it has at least 3:1 luminance contrast versus the surrounding non-link text. (See "non-inheritable" https://docs.python.org/3/library/os.html#os.dup)

 * http://www.w3.org/WAI/WCAG20/Techniques/working-examples/G183/link-contrast.html

Given that the surrounding text is #222, the a:visited color should be bumped from #30306f to #6363bb in order to meet the 3:1 luminance-contrast guideline while preserving the hue and saturation.

By the same calculation, the un-visited links are slightly too dark and should be bumped from #00608f to #0072aa
