Man, if you want to make a colorscheme sharing site, I'd love you. bytefluent.com/vivify/ is decent for creation, and http://code.google.com/p/vimcolorschemetest/ is good for seeing a staticish list of existing options, but a well-made site for sharing, finding, and discussing them would be pretty damn cool. :)

Looks like Vivify clobbers (or just doesn't output) terminal colors. Here's a tool to fix that: http://www.vim.org/scripts/script.php?script_id=1809

There might be better approaches, of course.
