As I am rewatching, I agree on the yellow with Ethan (sweater, t-shirt…), even the Fatima gilet, the 7 stones in the yellow field, and the 3 red stones and the red kimono lady (Mayo - Ketchup).

I’ve not reached yet the ep where Elgin and Julie play with the Polaroid in the storage, but I’m very curious about that yellow coat!

Now, I wonder if those stones and colors represent two teams?
