More fun with golds!
One key strategy I try to remember when I am working on golds is to mix in a bit of the yellow Vallejo fluorescent paint. Not only do I include it in "lighter" shades such as the highlights, but I will mix it in with my shadow colors too.
This means mixing it in with one of my favorite gold shadow colors, which is purple. That's a very natural shade to gold. I also had to be aware of what was around the gold armor, such as the cloak. As a result, I tried to sneak in a little red into my mixes.
A small amount of grey/green is also important, since using only various shades of yellow will make it appear more like yellow painted strips instead of shinier metal.
I think these views give a hint of how the colors transition depending on the shape an position. Light to dark shading, with the darkest shadow typically nearest the bright highlights also lend a hand in getting that shiny appearance.
Many of these strategies are discussed in my Painting Golds video, part of the massive Painting Pyramid series of instructional videos. I paint a Raging Heroes horse and rider, in some ways very similar to this.
As another side note, making the horse a neutral gray (tinted a bit towards the cool side) helped to make the warmer colors of the armor seem even more intense. The added impetus of the fluorescent paints sealed the deal!
