Legend of Zelda Headcanon:
All of the monsters in Breath of the Wild had wildly different and varying colors before being taken over by malice. After the goo took them over, it sorted them based on strength, and assigned easily readable colors to each power level so that Ganon could tell what strength of troop he’s watching at a glance.
Bokoblins, Moblins, and Hinox had more earthy toned skin, with greens, browns, and grays mixed together to help them camouflage and hunt better than the Crayola Red and Blue colors do.
Lizals and Keese underwent very little change in their coloration, though they were made more vibrant by the malice to more easily distinguish between the types.
Wizzrobes probably didn’t exist before the calamity started, though if they did, they underwent almost no changes.
Lynels got it bad though. The colors in their manes and the variation in their horse halves were wildly variable, with the mane having almost no limits as to what you could see, and the horse half only really restricting to the types of patterns naturally appeared. The markings on Lynels in game, rather than being a naturally occurring thing in the species, is a twist the malice pulled with Lynel’s tattoos and markings of pride, turning them into standard and uniform scrawls while on free Lynels, no too had the same tattoos and each mark really meant something.
Does this raise canon problems?
Absolutely.
I will not change my mind.
