not bad if your site uses those colors. beware the white text may be hard to read for some since it doesn't really pop out too much.
generally i try to stay away from those bright colors like that, but that's just me.
I like it...but if you use white text you might want to add a black border around it...and a little glassy gloss type of thing over the green part of it would look cool too...
glassy gloss would be good (say glassy glossy five times fast) but he said it's going to be black. So no need to comment on that, pretty good, you using an image map thing?
