Well I don't have anything agaisnt the color green either, it is in fact my 2nd favorite color, as you can see in my avatar, signature or whereever else.
It's just... Can't you make the corners of the green boxes a little more round? Or maybe a little lighter green tone (perhaps the same tone as the guide page)? I don't know if you can only choose from a list of box types on a "forum board settings" kind of thing or actually use boxes you made yourself, so I'm sorry if that comment was a little nosy.
