Stupid question: wouldn't the ND ("You may not alter, transform, or build upon this work.") part of the license basically mean that you can't use these colour schemes?
Someone who knows more about this should jump in and elaborate.
So those three are a go ;)
That said, I'm wondering what a /proper/ license for a colour scheme should be. If it's a css file (or even an emacs theme), that doesn't seem to be so hard to imagine.
