Bumper paint colour

[fireguyfire]

I’m going to sandblast and paint the rear bumper on my 1970 1/2 ton. My truck has the silvery grey checker plate top style bumper.
What colour are you guys repainting this style of bumper? I’m thinking an aluminum colour would be too metallic, but a grey would be too flat.
Any suggestions on a colour that will be close to the factory colour?

Those step bumpers are aftermarket, not factory. They are galvanized steel, so paint is not an original finish.

Cold galvanizing paint, of which there are many.

Thanks gents. I did read somewhere that the heavy duty style bumpers were an available factory option starting in 1970, but I’m not sure if that is correct.

There was a factory step type bumper in the later Sweptline era years.
