From what this explanation says the "true color" of gold isn't red; the color of metals in general when reduced to nano size is red. What a bogus way to present that information, in my opinion.

There's something called structural color as well. A good example of this is in the wings of butterflies. They display a wide variety of colors despite all being made from the same material. This is due to variations in the structure of that material at a microscopic level. If that material is ground down to powder, it is just white in color.

Well, the thin parts you get while hammering on it - gold leafs - is about 100 nm thick (you need 10 000 for 1 mm) and very golden.

Ripples are particles, huh. Maybe they dumbed this down just a little bit too much. Either that, or I'm watching an episode of Voyager again...

Alchemists when trying to create gold actually discovered.... A substance called... Green.... The first thing to be made from purest green was a broach.. And later a ring.

This kind of reminds me of the discovery around 2012 where adding very fine textures to metals could make them reflect different colors: https://www.gardnerweb.com/news/changing-metal-color-through-surface-texture
