Fauna Classified Question

Hey y'all... I was wondering if anyone knows what the different colors on Fauna Classifieds mean. I see some ads in green, some in orange, and some in yellow. Do those colors mean anything at all or are they just there for the heck of it? lol

When you pay to be a member you can highlight your ads with color....Just don't buy from the guy in red!!! JK! It's a highlight feature thats all.

AH! Okay. Good to know lol. I wasn't sure what they might mean, now that I know it doesn't mean diddly, I won't really think twice on it. Thank you!! :)
