Ehm, well, if I had been correct, I wouldn't have said 'PC', since a
LGP-30 is a 'PC', too, by the terms of its time ;-))
But IBM PC does not say anything about a specific graphics card.
You said 'any PC'. OK, I will read 'PC' to mean 'IBM PC compatible
computer'. thus rulling out things like LGP-30s, PDP8s, etc. You did
not, however, specify a video card. I therefore assumed that any
PC-compatible video card would work, and the original IBM MDA card is
one such.
In other words, a 5150 with an MDA card is a member of the set of 'any
PCs'

You can get "graphics" out of an MDA if you try hard enough. Lo-res, of
course (line drawing chars and 1/4, 1/2, 3/4, full shaded boxes in the
128-255 part of the character set).
Also, an authentic MDA display has green pixels IIRC, so there's your
colour. Or did you mean multi-colour? :)
