Vine's Expository Dictionary of NT Words

A — 1: πυρρός

(Strong's #4450 — Adjective — purrhos — poor-hros' )

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

A — 2: ἐρυθρός

(Strong's #2063 — Adjective — eruthros — er-oo-thros' )

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, Acts 7:36; Hebrews 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.

B — 1: πυρράζω

(Strong's #4449 — Verb — purrhazo — poor-hrad'-zo )

"to be fiery red" (akin to A, No. 1), is used of the sky, Matthew 16:2,3 . In the Sept., purrhizo, Leviticus 13:19,42,43,49; 14:37 .
