Green

Mine's red.Months later...Bob: Hey, I got you this green painting. I remember you saying your favorite color is green and I thought you'd like it.Alice: Oh. Um, that's nice of you, but I actually don't really like green. My favorite color's not green — it's blue.Bob: Oh. I coulda sworn you had said green.Alice: Oh, I think I did say green. But, um, Bob... you really shouldn't take things people say so literally all of the time.Bob: Blinks. I'm confused.Alice: Ok. Well, I mean, yeah, I think I did say green.

But why would you look at hue angles on a color wheel! We're humans!Bob: I wish I understood what you mean.Alice: Ok. At least in my experience, like, yellow is kinda gross.

Why... you seem confused?Dave: I mean, that just isn't very precise. It could mean so many different things. People measure color in various ways — wavelength, hue, physiological encodings, whatever. But whichever model you pick, just saying "green" only tells me so mu
