Code Red/Yellow/Blue/Green

[DarkLordSen]

Basically kill any demon with a lot of that color. The fire sprites count as well as other demons.

I'll post a list of demons that count for each color when I've completed all 4.

So far:

Red Demon :
Momotaro
Yellow Demon:
Shinlong

Amenobozu count as yellow.

[Null Winter]

Oddly, snow sprites don't count for either blue or green despite having both gradients in their palette.

Green is Dancing Lion. And maaaaybe Hitodama.
I’m a bit colorblind so I can’t tell if that’s green or not when it comes to hitodama.
But Went down that long tunnel that’s underneath that strip of bars/restaurants. They’re both located in that area and popped the completion notification
