Soothe Theme
This is a theme I use almost exclusively now, it's not Terminal friendly, and I should fix that, but if you're using Emacs.app on OS X, or in another full color window manager it'll serve you well.
The block-highlights may put you off, I find them very helpful for some reason I'm unable to clarify for you in any technical / psychological / color-theory sense, but try it out anyway.
Feel free to fork modify, whatever, it's MIT Licensed.
