Sets of simple skins recolors that you'll unlock for beating wave 50 in Simulacrum or beating a Twisted Scavengers or beating Voidling.
Most skins will be unlocked via this method.

Some of the weirder skins will be unlocked by beating the game with Artifact of Dissonance enabled or during a Prismatic Trial.
(Prismatic Trial provided by the Little Gameplay Tweaks mod or other mods)

A lot of colors are inspired by RoRR palettes.
