According to The Spider Restorers Guide by Chris Rees, the two "colours" close to what you describe are Aqua Blue Metallic or maybe Silver Metallic, probably the former. Both came in the '83-86 (USA) model years with "dark brown leather trim".

Took my '87 QV to a local automotive paint shop and they looked it up in their books and made me a rattle can of Quadrifoglio Verde that was an excellent match.
