Well, probably, but one of my main goals here was to make something reasonably fast for uses like the epidemic etoy. The existing colorSees was just too slow to be useful in this case and that's because it *does* render each morph to see if it contains a particular color in a particular place. Possibly more useful in the general case would be a "touches" variant that queried some attribute/property of each morph.
