Hello, hello.

I just got a scanner as a gift yesterday (BC60XLT-1) along with a frequency
book (Police Call 40th Anniversary); and I would like to ask a question or
two from the experienced scanners (is that the proper term?) out there.

I have searched a few websites, and read the books/manuals, but I can not
find out what the "colors" refer to. I'll use these listings for example:

Lompoc City of (Red Channel) 460.0500
Lompoc City of (Green Channel) 460.1250

Just what do the colors refer to, and are certain colors more viable (or
important) than others?

Thank you in advance!
