Each wolf in Beau’s pack--and some wolves outside his pack as well--has a wolf form that somehow mirrors who they are. I haven’t come up with all of their appearances yet. Only the ones who have shown up in some form so far.
Beau and Belle both have brown pelts, though his is a couple shades lighter than hers. Belle (if it’s my Belle and not @la-beaute-de-la-bete‘s) has a white blaze on her chest - this is already in my headcanons.
Adama has the same sort of build as Beau and Belle, but her pelt is chestnut in colour.
Lumiere is thin, lean, and has a blond pelt despite his hair being brown in human form.
Chip has a light grey pelt and one pure black ear, and he hasn’t quite grown into his body yet.
Cogsworth is barrel-chested, with a somewhat patchy pattern. The majority of his pelt is a mahogany brown, but his front paws are a lighter sort of tawny hue, and he has a patch on his back in the same colour with two thin splashes of black crossing it almost like clock hands.
Gaston’s wolf form is almost pure black, with a brownish red pattern over his shoulders and chest.
D’Arque is a gaunt, grizzled, dark grey wolf with white hairs on his muzzle.
