On the anime show Inuyasha, why are Sesshoumaru's markings sometimes purple or sometimes red?

Question

I was watching Inuyasha the other day, and Sesshoumaru's markings on his face were purple! Arn't they supposed to be..red? They sometimes are, but I thought they were always supposed to be red. Perhaps they're only red when hes mad?

Answer 1

well they are a type of purple, and depending on the scene (tone) they sometimes look more red or more purple.  Also if shading is involved or day or night and if people are actually doing their job at the animation studio.  :D

Answer 2

Shading :)

Accoring to the scene, the colours are adjusted to the background.

Answer 3

It's called total hotness. Haha, it's just the lightning and scene shades

Answer 4

it is not an error, it is the shading.

Answer 5

Just as everyone else is saying its just because of the shading. It just depends on the lighting and the kind of enviorment hes in.

Answer 6

It's called shading. The darker the scene the darker his colors will be.
