Jon - the "white dots" are from wear and fading [cleaning?], showing undercolor .... the top of the dash was a semi-gloss dark gray called "Charcoal " with no paint code shown on any sheet I've ever seen - the rest of the dash/interior was Marble Gray, original DUCO# 73604 ... the column, support bracket, shifter, ebrake and floor are the same "charcoal" but gloss ....
an original 57 dashBill
