Is there some error in the methodology using BluRay video files or something?
Pinkie's mane is actually a different color here than in the show, citing this: quasdar.deviantart.com/art/Vec…
Seems odd that they'd change the pony's mane -> human hair colors, but I guess not impossible.
It's just it makes things look a bit off since bronies are used to seeing the pony colored hair.
Is there any more authoritative way we can confirm this?
EDIT: Huahaha! What!?
So, I decided to check it out for myself, and in the Rainbow Rocks scene where it goes back to Ponyville/Equestria for a bit, I decided to compare Pinkie Pie's mane color from there, as well.We have a disagreement!:
The accepted guide here: quasdar.deviantart.com/art/Vec…
gives a color for Pony Pinkie's mane that is different from Human Pinkie's hair.
However, in Rainbow Rocks, Human Pinkie's hair has the same color as Pony Pinkie's mane!
This would seem to imply that Rainbow Rocks actually had a slight error in their pony colorations, since
Pony colorguide =/= Human hair color = pony mane color in Rainbow Rocks
And if we assume pony colorguide = pony mane color, then
pony mane color =/= pony mane color in Rainbow Rocks.
