There are some issues with the current Wikipedia favicon:
- No border around the letter, the W has direct contact with the surrounding
- The icon has no boundary, the white background melts into the usually gray surrounding
- The W is somewhat blurred
I have created an favicon for Wikipedia that addresses these issues, please see:
The W has a one pixel white separator and the bottom-right dark border gives it an optical boundary as well as a nice 3D effect. I have tested this favicon with different background colors (including black) and it looks good on all of them.
It would be great if you could make this (or a related version) the new Wikipedia favicon.
