I thought your second navigation (the one closer to the content) was broken for a second till I realized you went with a 2-color nav. Kinda cool but I would try to make the the bottom color closer to the top color so it doesn't appear broken to visitors.
http://digiex.net/ - I really need to work on the theme, I think the one i did on VB3 looked miles better. Had to start again with VB4 and never really had time to perfect it, especially for the CMS. Just need to find the time to sit down and do something about it.
They call that a monitor screen that is wrong configured lol (over saturated)
But I need to update it as I said and I want to improve the contrast with the bg and content but the text is dark enough and not a contrast problem in my opinion.
