Good point. Unless you also accept multiple answers. For instance if the 
inputted answer was /any/ colour chances are it was inputted by a human. 
I guess the spam robot algorithm could be set to look for keywords and 
them compare/associate it with some kind of related schema and add what 
it thinks are suitable values, but that is probably a little down the 
road. As there is no standard format for these things in the first place 
designers of these Capthca-alikes have carte blanche as to what form 
they take.

Cheers

Josh
