'White' in the Bible

"I had a vision in the night, and behold, a man riding on a red horse, and he stood among the myrtle trees that were in a ravine; and behind him there were red, brown, and white horses.

in the third chariot white horses; and in the fourth chariot dappled horses, all of them powerful.

The one with the black horses goes out toward the north country; and the white went out after them; and the dappled went forth toward the south country."
