Toolkit Plating All Clear Zinc?
 

I'm dropping off some parts to be plated tomorrow, and thought I would have the zinc plated tools in the toolkit re-plated as well (I believe some may be chrome).

At first I thought all the zinc plated tools were clear zinc, but looking at the fan belt wrench, it has a faint yellow zinc appearance. I Googled some toolkit images and all the tools in the pictures I found appear to be clear zinc, so I'm thinking the one wrench in my kit may have some slight corrosion giving it a yellow tint.

Can anyone verify if all the zinc plated tools in the kit are clear zinc, or if some are yellow zinc plated?

Thanks
