Well, to be perfectly frank, Quadra color video is still a long ways off as
of now. I'm the "guy working on color video" and I'm still debugging the
IIvx/IIsi/IIci video guts. When that's done I may add support for the
DAFB chip in most quadras or I just might pass the project to somebody who
has more time and better access to a Quadra.

The real trick to getting Quadra color working is understanding the DAFB chip.
Right now, I still haven't managed to locate where it is in memory!
