In the sitcom Mad About You there is an episode where Jamie tells Paul to put on a tie. Specifies the "navy blue one". "I don't own a navy tie." "Yes you do, it's the one that you think is dark green."

My wife and I go round and round about what is and isn't blue and/or green.

I have had similar conversations with my wife a few times, but I'm the one with working color vision.
