LOL... reminds me of my sister.... her DH had said that he only listens to half of what she says.... she came back with 'You are listening to the wrong half"...

Occasionally, DW will point at something and ask me "What color would you call that?"

I'll respond (maybe "purple") and she'll look at me as if I had three heads and say "Really?"

Occasionally, one of her friends will be there and also give me the "Really?" look.
This is not at all uncommon and is one of the reasons it is so imperative to get color management correct in photography and many other industries. The chances that you perceive the exact same shade of green in a tree leaf as another individual are remote, as I understand it.

At this site (aimed at photographers) search on "color management" in the upper right hand corner and you'll get hits on more than enough information: Cambridge in Colour - Photography Tutorials & Learning Community

And of course being able to give a numerical value to any specific color is important in industrial applications and advertising. The specific color of blue in the Ford oval emblem has a number, as does the brown on a UPS truck.

Everyone has seen a wall of TVs in a department store tuned to the same station and all or most showing different colors of the same scene. That's because they are not color calibrated. That's also why on some web sites where color is important they'll tell you that unless your display is color calibrated you will probably see incorrect colors.

I heard the call to do nothing. So I answered it.

Back maybe 52+ years ago I moved to Melbourne, Australia, from South Australia - the police in Melbourne at that time administered the driving tests - I 'failed' the color tests, and even though on the road test, I could correctly identify the status of each traffic light, and my driving was (virtually) faultless, I was failed by officers (who I suspected didn't want any 'blowback' should I be involved in a subsequent accident).

A more sophisticated color test, (ordered by the cops), showed that I perceived red darker than 'normal' people would see it.

Final road test - there's me and three cops, (one of whom was a sergeant), going through the "What color are the lights two intersections ahead?" routine. I'm nervous as hell, but doing well - although still suspecting they're going to find an excuse to fail me.

Sergeant says "Pull around that corner and stop at the curb".......turn the corner and the curb has a solid yellow line, so I think it's a 'gotcha'.

"Sorry, can't stop here, solid yellow line" I said, and kept going.

Sergeant says "When I tell you to stop, you $#@!* STOP"........turns out he wanted to buy some cigarettes.

I got my license.
