Which gold? I've done some with our athletic gold, our university gold, and the a bunch of others with various gold shades.
I think with my mocks, most of them, the gold is truer, because these mocks are done in 1D (1 dimension) as is the cardinal (although I've made my cardinal very slightly darker than our athletic pantone. Many of the other mock releases have been shaded and too dark. I am trying to use our athletic pantone colors, for the most part.
For example, Joe Summers mock here is too dark.

The cardinal and gold should be lighter. Mine are lighter and truer. You can take my mock and darken the brightness, and you would have Joe Summers color. It's the same between looking at a uniform in the daylight vs. evening. The evening is going to look darker.
Back to the mocks, I'll get back to the gold pant soon. I'm doing the white pant first, then will shift to the cardinal. I would love for them to do a gold pant, but if they did, I fear it will be the too bright athletic gold/yellow everybody (most folks anyway) don't particularly like.
