A: Hi! Is there a specific car you're looking for?

B: I'm looking for a convertible.

A: We have a wide selection right here.

B: I don't see what I want here.

A: Really? We have over 100 convertibles.

B: I'm interested in a purple convertible.

A: That's a rare color in any car dealer.

B: I guess I have to go elsewhere.

A: Don't go! We have colors close to purple!

B: Like what exactly?

A: We have blue cars.

B: Blue is blue. Purple is purple. Good-bye.
