Pretty sure they are gold iridited .  Later cars are sometimes grey or black phosphate Keps nuts.

Generaly Zinc & Cadnium Plating is or can be; Post treated rendering the "GOLDISH" finish.
Hexavalent Chromates
These can be applied to electroplated parts after the plating process has been completed.  As a result the corrosion, wear and abrasion resistance of the part are dramatically improved.  These include clear, black, olive drab and yellow.
