I don't know if this qualifies as a request but like,, I've never understood how to do troll bruises bc the blood colors aren't like human blood colors obv so I don't really have a basis?? Can u foist some magic off on me pls

so like, i have some standard colours i use for beating up humans, w the purple and dark red on a multiply layer, the yellow on a lighter multiply, and the bright red on a normal layer w low opacity etc the bruise is basically jus t, a blotch w a water brush

for trolls i guess u would keep the yellow but change the purple to a somewhat nastier version of the actual blood colour, like a few hues across until it looks good but still the same shade as the purple. eg (i was too lazy to edit in horns lmfao):
