It's impossible. Just like we can't imagine a colour that doesn't exist without thinking of one that does.

blue is cold
red is hot
yellow is happy
pink is girl
orange is pumpkin
black is eyes closed

It's like different textures or different sounds, but for the eyes.

With tastes
I'd say pink is bubble gum or whatever.

With smells. 🍒🍑🍐🍏🍎🍋🍌🍉

I read an article once where a blind person had a near death experience. During it she saw colors and explained them as different shades of bright.

Interesting question. I don't know.

They are definitely Worth seeing?

Why should you?

Unless the person had sight at one time and then lost it, there will be no concept of color....so trying to explain it will be an exercise in futility.

It can’t be done

I wouldn't. Theyd be like, "why is this dumb bitch talking to me?"
