Patrick (H) Willems’s video essays on color in film; specifically his ones on

I thought he had one on John Wick too but I can’t find it. If you like saturated colors though, check that movie out!!
those are only a couple of exterior references, there’s lots out there!! so good luck & I hope this helped!!
