Marty, I suspect most or all of the common series have color variations. I've got a bunch and I know Dan McKee has many more than I do.
I've yet to notice a color variation in the short print series but I haven't handled nearly as many of those as the common series.

Other than the white Musial I"ve not seen a premium placed on any color variation. I don't think any particular hue is any more difficult than another.
