OP I think we've got a good enough consensus for changing out the voting icons and the visited link style. Feel free to submit a pull request, or I can do it instead if you prefer.

We will need a day mode version of the icons too, where the white is black or off-black instead.

Edit: another issue is that the orange you chose is very close to an existing orange (like the highlighted tab on your profile page). So which orange should we use? I figure all of these oranges should be the same. Both oranges are visible here: https://saidit.net/s/SaiditCSSthemes/ Especially if you friend anyone on that page, the two oranges look very clashy.
