[Coco] Documentation of "complex" artifacting (i.e. more than black/white/blue/red)?

[Arthur Flexser]

I wonder if your test program would look any better if you reversed the
artifacting.  Doesn't holding down F2 (or is it F1?) and pressing reset do
that on a CoCo 3?
(Accomplished by resetting the palette register values, I think, to mimic
what happens on a CoCo 1/2.)
