Depends. If your color is based upon some pigment, then yes, you'd have to
do the 1x1 image thing. If by color you want to know which object you've
hit, you can also just use trace() on the different objects, and sort the
results with whatever sorting you need.

BTW <shameless plug> I've just recently written a set of Macros entitled
"Surcoat Macros", which might do that point-cloud-thingy quite well
</shameless plug>. :-)
