If you have Object Desktop, but the Object Desktop discount theme. It comes with a MyColors version, and also has an extra download for the Theme Manager theme.
I did this, and have used the .suite file that was available. I like the theme (very nice graphics and skin coverage), and it works fine on Win7 (no issues, and I'm guessing that if there are any updates, they'll be made available as usual).
One minor nit to pick, though, for those who aren't OD subscribers:
From the way KarmaGirl's post was worded, it appears that if you don't have OD, you're stuck having to use MyColors.
Which seems pretty silly. Even Brad said (in his post about 'Tough Love for Object Desktop') that all future content would be available as a theme, which also implies that it would also be available to anyone who at least had Theme Manager (though the independent parts should still be usable, if desired), and would not require 'MyColors'.
Given the stated future direction of Stardock, for suites and themes (and so on), why are you still packaging these as MyColors themes at all? What's the point? Keep it (as Brad mentions) for your enterprise and OEM efforts, and get rid of it entirely here.
