I think it'd have been cooler if Breath of the Wild had an oil paint art style like the promo art has. I'd have much preferred it over the generic anime cel shading art style the game actually has.
This palette was approved by Araki, though, because the colors for Di Molto Bene's Statue Legend series credit Araki as the color supervisor just like the Super Action Statues. It's why several of the palettes for these figurines reappear in the anime.

It's interesting how persistent this palette is compared to his JOJO A-GO!GO! palette considering that it isn't even a palette made by Araki and that it only first appeared in 2008.
