Any name that fits a bun's looks and/or personality, preferrably both.
Musti's name was more for looks and didn't translate into personality, but by the time i'd realised he'd already learned to come when called, so yeah. Storm's name is perfect, the silver&gold-tipped coat with a black base and broken white is just mmmh. Even when he's calmer he still has some storm aspects. Lümi's name was perfect too-cuddly, kissy, silky white bun soft as snow, just some black spots as if spring was coming. Iris' name fits her more for looks and less for personality, though miss grunty-stomps is sometimes overly cuddly and sweet like iris the candy.
My avatar pic of Nikki, on her back, sound asleep, all four legs in the air, mouth open and tongue sticking out--She was a very different bunny and I really miss her a lot. TPBM, what is your favorite outdoor scene?
