SOLVED. YA dystopian fantasy novel, people sorted with colours according to their intelligence, told from the perspective of a young girl, critique of meritocracy and classism. [s]

[Brontë]

I read this book when I was eleven or twelve years old, so I believe it's young adult. So, it was 2008/2009/2010.

Consider all of this plot SPOILERS, I'm just going to write out as much as I can remember from the plot:

I believe it's told from the perspective of a young girl. The society is one that exists in colours - they wear a specific colour to indicate their social class - the most intelligent and "deserving" live in high society with access to food and resource etc, their colours might have been white, blue and, purple. The unintelligent and disabled, considered least deserving live in slums, the lowest having to wear all grey. I think all families stay together.
Main character starts off in orange, which is a meh colour, not particularly well off, but not living in a slum. She has a brother. I think they may have been demoted to 'grey' after failing a test or something.

I remember the main character points out this strange sculpture, completely different from everything else, that has a ringing bell sound as the wind passes through it.

There's also a part where the main character sees something she shouldn't. I think it was a people being tortured/brainwashed.

The main character, her brother, and another boy either get kicked out or flee outside of the city into a swampy marshland. In this marshland they meet a group of rebels living underground (maybe.)
The characters are sent onwards, I believe they hitch a ride on a pirate ship, something goes down.

I cannot remember much else. If anyone has any information that would be great.
