Post Timestamp font color?

[HerbToken]

How would I change the text color of the timestamp for each post in vb 4.2.1 (to the top left of every post, it displays the time the post was entered, but the text color is white on my site and thus unreadable).

Thanks, but I cannot seem to find this under style manager.

Hmm, I've found it in postbit.css but it only changes the day on not the time that follows. Any suggestions? Thanks in advance!

I've just changed the background to silver so that the white text can show.
