A cool guide Blood Hue Directory

apparently so named because their shape is a vague resemblance (honestly I dont really see it more than other worms but whatever)

I mean, really! Just because I wish I had purple blood doesn't mean I want to be a penis worm!!

Edit: Fuck, I actually sent that comment into the fediverse...

Based on the molecule map thing green and purple are still iron based.

Looks like the green one is nitrogen and the purple is a mix of nitrogen, iron, and a nitrogen/hydrogen molecule
