I know there was some interest in mixed colors. I don't know how possible that would be, but if there was a chance, and enough people were interested, they could try for the classic two tone look of early plastics. Worst case is you get something like the colors mixed incompletely into the clear.
I don't know how it works, could a translucent mix be made and then have opaque or shimmery colors be added without fully mixing them in with the original mix?
It would also be cool for colored translucents (like red and black), or getting the gunmetal or dark grey many of us want, or even the white or beige a handful like. I wouldn't pay $50ish for beige, but I might pay a little premium if it looks right to me. I need to check the renders again. If we got extra cases it might result in experimenting with add on hardware, such as the hot topic of a camera. There have to be other interesting ideas like that.

@Grench mentioned putting the camera in a sidecar. Maybe a simple mod can be made so that you buy a few holes in the side of the case (hmmm, typing...) and we can make a starting side car design that people can edit to suit their needs and print.
