Having the nature or appearance of flame; resembling or consisting of flames.
From Latin flammeus (flaming, fiery), derived from flamma (flame), with the Latin adjectival suffix -eus meaning 'of or like.'
The Romans used 'flammeus' to describe colors—red hair was called 'flammei capilli' (flammeous hair)—showing how they saw flame as the ultimate reference for anything glowing or brilliant red.
