The original color is really nice; but, what does that matter sans any plans to sell?
I'd try to stick to an OE period correct MBZ color if there is one you like. Pick the color that makes you happy and start sprayin' just do it really well as you stated.

Please post pictures if you move forward with the project, good luck!!!
