Etymology 1

Borrowed from French chromatique (chromatic) or directly from its etymon Latin chrōmaticus, from Ancient Greek χρωματικός (khrōmatikós, relating to colour; one of the three types of tetrachord in Greek music), from χρῶμα (khrôma, colour; pigment; chromatic scale in music; music) (ultimately from Proto-Indo-European *gʰer- (to grind; to rub; to stroke; to remove), perhaps in the sense of the grinding of pigments) + -τῐκός (-tikós, suffix forming adjectives);[1] analysable as chroma +‎ -atic.
