Should dark blue really be the background colour for this website?

Blue is a really nice colour. I love the layout of this website. And I love the way this website works. But this shade of dark blue kinda sucks me into the screen and makes me think of the deep blue lonely ocean. I mean.. I know that we’re also trying to emulate the sea because of the fluther of jellyfish thingy. But why not use a shade something like the blue in coral reefs (think Finding Nemo)?

Of course, it may just be me, but the dark blue colour depresses me somewhat.

P.S.
I’m not trying to be an upstart here, but it just strikes me as someone new to this site.
