color change caused by salts/ions
Etymology
'halochromic' originates from Greek roots via modern scientific coinage: specifically from 'hals/halos' meaning 'salt' and 'chroma' meaning 'color', combined with the adjectival suffix '-ic'.
'halochromic' was formed in modern scientific English (New Latin/Modern Greek-derived coinage) as an adjective from the noun 'halochromism' (the phenomenon) and ultimately from Greek elements 'hals' + 'chroma'.
Initially coined to describe the technical phenomenon of salt- or ion-induced color change, the term has retained this specialized meaning and is used mainly in chemistry and materials science contexts.
