YA book main girl has power to change her appearance to look like other people, also has bright turquoise (?) eyes, is part of group of teens with powers and coloured eyes (purple, amber etc)

[N]

all i remember of the plot is that this girl can change her appearance to look like other people and in this group of superpowered teens shes in they get sent on mission things and in this book she gets sent to take the appearance of a normal rich girl because this girl is in danger, potentially being stalked/in danger of being killed?
and in the group shes in the other teens have superpowers and coloured eyes, i remember one of them definitely had purple eyes and then another potentially had amber/gold eyes? and one of them maybe could manipulate electricity/lightning?
i think there was a scene with her in a pool at some point maybe
i think the main girl had ginger/red/strawberry blonde hair and distinctive turquoise eyes
i definitely read this book pre-2015
anyway if anyone can help at all i would send you so much love <3 i'm being tortured by this

Is it The Girl With the Silver Eyes by Willo Davis Robert’s?

Maybe Impostor by Susanne Winnacker? It came up searching online. The main character describes herself as having turquoise eyes and auburn hair. It was published in 2013. I used the "search inside" option in Google Books to check: https://www.google.com/books/edition/...
