I have spent a decent amount of time at SO, so I wanted to venture off to other parts of StackExchange. (Yes you can read this as wanting to boost rep). I have found other sites have bad color and/or font schemes.
(this is in no specific order)
- Beta scheme, the color for unvisited links have bad contrast (2.8:1). A good ratio is 4.5:1
- Programmers, again unvisited links, and the font choice just for the body text makes me want to leave in seconds.
- Android, the color for links (from a glance visited and unvisited are #83a127), again a bad ratio (3:1)
- WP, Some contrast issues site wide.
It's a fairly common problem for link colors to be of very low contrast with other text or to the background, making them either hard to read or hard to distinguish from non-link text.
I used WebAIM's Color Contrast Checker to get the ratio information.
Please re-evaluate the color link schemes that are chosen for various sites to ensure that they are readable and distinct while maintaining their general color schemes. Ideally schemes should pass at a minimum WCAG AA compliance.
