Chromovelato is the generic Italian terminology for applying a transluscent colour coat over chrome plating. It was probably most popular in the early 1980s with several manufacturers (Colnago, Scapin, Moser, Bartali, etc.)but goes back further. I recall boom era Torpado with the finish. I believe it was orignally developed as an improvment on Legnano's transparante verde, which was their famous transparent green over silver paint.
