Wow, I really have to take the occasional nap.

Ty for your comment, it lead me to the answer. First, I didn't realize I had the colon ':' in the wrong place. After that, I realized I could use the original code:

Code:
color brightblue "//.*"
And then just correct the url problem with:
Code:
color brightyellow "://.*"
As everything that would contain a url (or '://') would have to be a string.

Ty for your assistance.
