I just tried this with Perl, and it looks great (the fold-column's a bit bright, but I don't have that on by default). Have you thought about uploading it to vim.org?
I am sitting on a mostly-done vim version right now as well, the GUI colors are all good, but I wiped out the terminal colors (I want them to just be the defaults). I'm not exactly a vim expert and I almost always use the terminal vim exclusively for git commits, which don't really need highlighting, so the motivation to fix those sort of disappeared.
Thanks for the kind words about molokai; took a bit to get it ported, but I've enjoyed it a lot since then. 99% of the props should go to the original authors of monokai and Hamish, though :)
Molokai ain't perfect, but I have yet to find one I like more for daily use.
is there a reason why most of these color schemes (including solarized), have a very low contrast for comments - making them difficult to read.
I personally use the desert colorcheme (http://hans.fugal.net/vim/colors/desert.html)
I mostly use IR_black for vim and emacs, that's definitely a classic. But I'm also quite fond of a custom scheme I made; the colors mostly come from Textmate's Made of Code scheme. Here's a screenshot:
I am currently using darkspectrum[1] for diff output and candycode[2] for everything else. There is a huge gallery of them, viewable with several code samples, on the Vim Color Scheme Test page[3].
I use molokai as well, but with some small tweaks (darker near-black background, lighter more visible comments, and a more visible line highlight). Inconsolata font for life, I've tried just about every other programming font out there and I always keep coming back.
My favorite for gvim/MacVim is molokai: http://winterdom.com/2008/08/molokaiforvim , seconded by vividchalk when i'm on the terminal: https://github.com/tpope/vim-vividchalk
Haven't found any good color scheme for iterm2 yet. Currently i'm using thayer: http://ecto-plazm.deviantart.com/gallery/
