Yes, but this is getting very theoretical, now. Adding an existing
color video card for an external display to the SE/30 is much more
practical and doesn't disturb the SE/30's unique look. :-)
:wq! PoC
Even then not.
The picture of the phosphor stays monochrome,
regardless of anything in front of it.
I think Tony's point (pathological corner case though it is)
is that a B&W CRT *can* display color with such a filtering
device; it's how early color TVs worked. The SE/30 has no
method for doing so on any existing video controller, though
I suppose one *could* make such a card if one were suddenly
in possession of far too much spare time.
Come to think of it, I believe it's also how modern DLP
projectors work as well; if you move your eyes fast enough
on a DLP projection, you can see the individual colors
as ghosted images on your retina. It's not a CRT, of
course, but the color concept is the same.
