You could, but that would be missing the point of the whole honesty exercise by using an overly restrictive definition of lying.

In 'Lying', Sam Harris defines a lie as an intentional act of deception (or something like that).

That definition fits your suggested responses and I would call them lies.

Answering "No, but I think the colour matches your eyes", on the other hand, would not be deceptive, assuming you did believe that.
