Yo, I think I’ve got the CSS sorted out. It’s based on Yotsuba A.
http://pastebin.com/RfajUjg7I added styling for character tags in case you ever want to use it. Plus you can always add extra tag types on your own if you want, it's not that hard.
char: or _(character) will make a tag green
artist: and _(artist) make it red
series: and _(series) make it purple
meta: makes it orange
artist_request, character_request, copyright_request, translation_request, and translated are color coded.
I also made year tags all the way from 2003 – 2030 orange by default but it's probably overkill lol.
And lastly I highlighted your account name to be red and have "## Admin" after it. If you Ctrl+F for "refinder" you can remove that part if you want, or replace it with a different account name.
You and anyone who has visited this booru before will have to clear their cache to see the new stylesheet once you replace it.
