'warm-colored' originates from Modern English, formed by combining the adjective 'warm' and the noun 'color' with the adjectival suffix '-ed'; 'warm' ultimately comes from Old English 'wearm' where the root meant 'having warmth', and 'color' comes from Latin 'color' via Old French 'colour' where 'color' meant 'hue'.

'warm-colored' developed as a descriptive compound in English by joining 'warm' + 'colored' (the past-participial/adjectival form of 'color'); 'warm' changed from Old English 'wearm' and 'color' passed into English through Old French 'colour' from Latin 'color'.

Initially the elements meant 'having warmth' (warm) and 'hue' (color); over time the compound came to mean specifically 'having warm tones (in color) or giving a warm visual impression'.
