'Red' in the Bible

Another came forth, a red horse. To him who sat on it was given power to take peace from the earth, and that they should kill one another. There was given to him a great sword.

Thus I saw the horses in the vision, and those who sat on them, having breastplates of fiery red, hyacinth blue, and sulfur yellow; and the heads of lions. Out of their mouths proceed fire, smoke, and sulfur.

Another sign was seen in heaven. Behold, a great red dragon, having seven heads and ten horns, and on his heads seven crowns.
