The first bun is a tort,
possibly a blue tort (but I don't really think so.) Are the second bunny's eyes pink or brown? If they are pink, it's a Himi/Cali/Pointed White.
Oops, maybe I'd better explain that! Himi (Himilayan) Cali (Californian) and Pointed White are different names for the same color, a white rabbit with pink eyes that has color on the nose, ears, paws, and tail. There are two breeds (Himilayan and Californian) that are exclusively that color. There are a number of other breeds that may be that color, but what do you call them? Well, that depends on the breed. In Jersey Woolies, they are (or at least were) Pointed Whites. In Netherland Dwarfs, they are called Himi's. In Mini Rex, we used to call 'em Cali's, but now they are called Himi's. Confused yet? So were the judges!! There has been a movement afoot to get
all animals of that color called by the same name (Himi), but it has met with mixed success.
Himi is a weird color. It is temperature dependent, with the dark pigment appearing on areas where the skin temperature is cooler. During the cooler months, Himi's usually have very intense, large areas of color, with the nose marking spreading over much of the rabbit's face. When the weather is hot, the area covered by the markings shrinks, and the nose marking may be limited to just the end of the nose. (I had a broken Himi Mini Rex that had elbow spots, but only during the Winter.) Himi does will sometimes show dark areas where they pulled fur for a nest, and the skin got cooled before the new coat came in. Himi babies that got chilled a bit in the nest frequently show dark "ticking" in their coats, sometimes even resembling Frosted Pearls until their junior coats grow in, and replace the ticked hairs with hairs that are completely white.
Sable Points have brown eyes, and dark "points" (nose, ears, paws, tail) on a background of cream (not white) colored body fur. In the third picture, i am assuming that is bunny # 2's face on the far right, it looks very white compared to the other two bunnies in the picture. If bunny #2 has brown or grey eyes, and white fur (with or without ticking) then it is a Frosted Pearl (also called just Frosty.)
Oh, and just for the record, bunny # 3 is the Chestnut Agouti!
