This is probably simple, but how do you change the color of just the arrows in the page navigation links? Thanks!

Currently there's only black and white, see menu tab "Page Menu Bar"

I must not be calling them right, I mean the little arrows in front of newer posts (<< newer posts) in the footer. Right now the whole thing is green, and I would like the arrows to be a different color than the text.
Thanks!

I thought you mean the down / right arrows in the horizontal menu bars

To change the color of (only) the arrows in the page next/previous navigation you'd have to do this inline as those arrows don't have their own class.

At A. Theme Options -> Previous/Next Navigation -> "Older Page" link on MULTI post pages change the content of the text field to i.e.

Older Entries <span style="color: #123456">&raquo;</span>

See next post for additional info on how to make this work

This does currently not work and will be fixed in 3.2.1 see http://forum.bytesforall.com/showthread.php?t=603 post #2 last part, for a temporary fix
