Update to my last post:
Possibly the PAL version had only monochrome composite video; I
wouldn't know.  The NTSC version definitely had color composite
video. 
 
Possibly.  PAL is used here in .au, but most Apple ][e are NTSC.  If you
wanted color you either bought a PAL card, RGB card and monitor or Apple's
not-quite-NTSC (which doesn't produce a color picture from other NTSC
sources) color monitor.
Even so running the RGB output of the IIgs through a scan doubler will give
a better picture on a VGA CRT monitor than using the running the composite
output through a TV card.  I've read that scan doublers don't work well
with some LCD monitors, in that case using the TV card maybe a better
option.
