Hey, thanks for posting. Looks interesting though a bit distracting. When I first started looking for and messing with themes I came across one that had a pretty good idea behind the styling. It had a palette ranging from dark to light and the importance of the element being styled decided how bright or dark it would be styled as the eye is naturally drawn to things that are brighter.
You can find that theme at: http://wiki.macromates.com/Themes/UserSubmittedThemes. Scroll down to Dominion Day to get a look at it and the basic idea behind it.
Perhaps you could mess with your theme and make it a bit more usable, but if you're happy with it that's all that matters.
Feel free to post a link to download it and I'll add it to the list :]
