Wait wait wait... one last brainstorm for a new color scheme:
All opaque versions of some standard colors.  Or maybe 4 opaque with the one 
new/last translucent color:
Opaque Blue, Opaque Red, Opaque Green, Opaque Yellow, transparent Magenta.
No, I don't think this is the silver bullet idea... just something more to 
chew on.

We've had a lot of internal discussions about all these color scheme 
issues and right now our feeling is that none of them really "work." So I 
apologize for getting your hopes up about new colors, but right now we're 
just going to focus on keeping the existing versions in stock. Sorry.
