metallochromen.

Brit.

/ˈmɛtələ(ʊ)ˌkrəʊm/, U.S.

/ˈmɛdl̩oʊˌkroʊm/; see also metallo- comb. form.

Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: metallo- comb. form, -chrome comb. form.

Etymology: < metallo- comb. form + -chrome comb. form, after French métallochromie metallochromy n. In sense 2 after metallochromic adj.

†1. Prismatic tinting imparted to a metal surface by electroplating; an instance of this. Cf. metallochromy n. Obsolete.
