YA Book set in Dystopia I think where girl can't see any colors

[Christina]

I read this book around 2015-2021 I think? It was an early 2000's 2010's dystopian novel, I just remember a part where the girl, who could only see in black and white, gave a description of all the things she could see in a whole range of shades of gray. They were names like cloud gray, dolphin gray, light gray, etc. and it was a whole list of them in a paragraph. I'm trying to write a book with a girl who can only see this way and would really like to find these color descriptions I've been searching for ages with no avail.

Furthermore?

[Christina]

no, that’s not it. I think it was more of a realistic dystopian? maybe not dystopian but Earth? Sorry this is not too helpful

[Rainbowheart]

I really should know this!

I don't think it's anything else on the Colorless World list.

[Christina]

yeah it’s not there. It might be that the world isn’t colorless she just can’t see it. like can’t see color unless you meet your soulmate? or something else??

the giver?

[Christina]

not the giver, i think it was from the point of view of a girl

[Rainbowheart]

Was the girl a teenager or a younger child?

Shades of Grey?

[Rainbowheart]

The Extraordinary Colours of Auden Dare?

The MC is a boy, though.

Shades of Grey sounds like the best candidate so far.

"The human race has transformed into an androgynous-looking race of people with very small pupils that can see one and only one color, all others appearing as shades of grey. Your social standing depends entirely on the one color you can see; those who see purple belong in the aristocracy, whereas those who see red are the working class. Achromatics, or "Greys", cannot see any color at all, and thus they're little more than slaves."
"Eddie falls head-over-heels for a feisty Achromatic named Jane, whose violent temper is as rare in Chromatacia as is the shape of her nose."

The Splintered Light?

But it's another boy MC.

[Susannah]

I would guess The Giver, except, I don't think there were any dolphins. The male protagonist can see colors but no one else (male or female) can see colors. Only the Giver and the boy he is training can see colors.

[Rainbowheart]

Christina already ruled out The Giver in message 7.

[Rosa]

The Secret Horses of Briar Hill?
Shadowed Flame?

[Rainbowheart]

Daughter 4254?

[Rainbowheart]

Greylands?
