G'day Zivley,
Mate, the colours refer to length of members. If you're light green, it means you're very new here and helps older members know to take it easy on you, and advise you of such things as the "search" button, etc.
After you reach 1000 posts, you go dark green, which means you've been aroundlong enough to have gained credibility on the forum and now you are entitled and expected to let other newcomers know about the search function. It also means you can spout off about any bloody thing and your opinions will be taken as the Gospel truth (except by the guys in the Sacred Sax section, but there's only two of 'em, so who gives a fig?)

After you've posted so many times,that your post count goes around the clock and back to zero like nanna's old morris minor, you'll appear blue.
This lets everyone know that you're older than Moses, in forum terms, and whilst you've been around here longer than Gary, and have mucho credibility, you're also a geriatric sax player and can't be trusted to remember your own name. Let alone what you were originally arguing about.
If you should perchance, post something XXX rated, insulting to another member, political, religious, (with exception of the sacred sax thread, which has SFA to do with sax but that's an argument for another day), or otherwise naughty, your colour will change to blend invisibly with the background and you'll disappear. Around here, we call it getting "Martysaxed."
I hope that's cleared it all up for you mate. Anytime I can be of help, don't be afraid to ask.
