I think your OS X color profiles may be crap, as the background is GRAY, not pink.
...if you happen to be on MSN any day soon, I could hand you the full color palette for this project. POTENTIAL!
Remember: I sucked at illustration. Outcome of going there: I became an even more minimalistic typographer kind of person.
