Zinc plating conductivity comparison

Q. Hello,

I am looking at plating for a sheetmetal (CRCA Steel) bracket which is used for mounting a PCBA. This plated bracket should have very good conductivity for ESD purpose. The finish I am looking at is Zinc Plating 8-12 microns thick. I would like to know which passivation would be more conductive (Blue or Yellow or any other). I would be very thankful if someone could guide me on this topic.

Thanks,

A. Blue (or clear). In other words, the thinner the better.
