The scales have a really cool metallic sheen. The turquoise blue and emerald green ones look insane, but I also liked the lilac, slate, purple and silver tones. It's a similar colour palette to when petrol has spilled on the floor and leaves a green and purple sheen on the ground.
The fish reminded me of one of my favourite childhood books, The Rainbow Fish by Marcus Pfister. The story is essentially a tale of socialism as one fish who happens to have been lucky enough to have been born with amazing scales gives them away in order to share these wonderful scales amongst all fish evenly. I used to love reading it to children when I worked in a library because not only do I have such fond childhood memories of the story but it is also a really good way to talk about sharing. Politics aside, the book is really beautifully illustrated and the watery-metallic colour palette has a really dreamy quality.
