Okay, I just did two things.
First I did the color test thing to make sure my eyeballs are working correctlys. Turns out I have perfect color vision.
Proof!
Then I saved the picture, and ran it through the Selective Color adjuster in Photoshop. The gold that's supposedly black? It's gold. It responds to changes made under red and yellow selections, not neutrals and blacks.
The white section does have a blue tinge, so it responds to changes made under blue. It's still mostly white, though.
So I'm calling BS for computer verified reasons.
