Painted or anodized wheel nuts

Working on building up a BBX for my son and he's asked for a gold and black color scheme. I'm going to strip the chrome off the wheels and paint them black, and I'd like to add gold wheel nuts to add some nice contrast.

It'd be great to match the wheel nuts to the PS-13 gold paint for the body, but I could also chase down some gold wheel nuts.

What do you guys recommend? Would it be OK to paint the hardware, or is it better to find anodized nuts?
