Red

denotes "fire-colored" (pur, "fire"), hence, "fiery red," Rev 6:4, Rev 12:3, in the latter passage said of the Dragon, indicative of the cruelty of the Devil.

denotes "red" (the ordinary color); the root rudh--, is seen, e.g., in the Latin rufus, Eng., "ruby," "ruddy," "rust," etc. It is applied to the Red Sea, Act 7:36, Heb 11:29. The origin of the name is uncertain; it has been regarded as due, e.g., to the color of the corals which cover the Red Sea bed or line its shores, or to the tinge of the mountains which border it, or to the light of the sky upon its waters.

"to be fiery red" (akin to A, No. 1), is used of the sky, Mat 1:16-3. In the Sept., purrhizo, Lev 13:19, Lev 1:13-43, Lev 13:49, Lev 14:37.
