It did this on the basis of a data base of thousands of images. It
must have had color sensitivity of some kind as, for example, it could
tell the difference between a large white-walled building and a snow
scene.

So you're basically saying that there's no way to detect the
difference between a large white-walled building and a snow
scene without colour sensitivity, not even by seeing that the
snow scene was much brighter than the building?

But was it much brighter than the building?

So why do you think snow is a different colour than a white
walled building?
