I don't see why... I've been able to do almost any color scheme from textmate or other editors. I have my favorite color scheme from textmate in VIM (Sunburst). Just make sure you're either using gvim or your terminal has 256 colors turned on.
The 256 color thing is the most important and was something I struggled with for a few years before I figured out the problem - on Linux it was always fine, but on OSX, wow it was bad. Couldn't figure out why till someone else said the fact same thing - 256 color mode.
The syntax schemes just either never have the number of unique keyword(-types) available or I assume since it's the case for every language I use... it's not possible with vim. If it is, then I lament the inferior set of default syntax highliting.
And yeah, I use gvim for the greater color palette. I'd take a screenshot, but my current tether is on 3G and my server is taking too long to launch Gvim over X
