'Red' in the Bible

In the night I saw [a vision] and behold, a Man was riding on a red horse, and it stood among the myrtle trees that were in the ravine; and behind Him were horses: red, sorrel (reddish-brown), and white.

The first chariot had red horses (war, bloodshed), the second chariot had black horses (famine, death),

“And they will pass through the sea of distress and anxiety [with the Lord leading His people, as at the Red Sea]And He will strike the waves in the sea,So that all the depths of the Nile will dry up;And the pride of Assyria will be brought downAnd the scepter [of the taskmasters] of Egypt will pass away.
