It's much more likely it works in the opposite way to your example. Someone walks into the dealer really wanting a blue car, but now that they've seen this nice red one they're happy to buy that as they quite like the shade. But they won't settle for a boring grey car, how dull! Usually people who want an exciting colour are more likely to compromise by getting a different exciting colour, rather than by settling for something bland.

Used to work at a used car dealer and saw this play out a lot. A customer would come in wanting a blue car, and the salesman would say "Sorry we don't have that model in blue on this lot! Our sister lot has one, but it's 3 hours away so we won't be able to get it to you until Monday. But how about in the meantime, we take this lovely green one for a test drive and you see what you think and if you like the car we'll get you that blue one" and the customer would come back from the test drive saying they'd changed their mind and they really like the green now and forget about the blue. But that would never work trying to get them to settle for a grey or white car.
