First order color in good lighting is easy: is this sweater red or blue. Much harder "does this scarf match this sweater". text recognition is only solved in pretty well controlled situations also. Contextual adjustment in situations like this is something humans are really good at. You can easily imagine an automated system that works for some of these things, but is much slower and harder to use.
