Well, hold on. Gold is a specific color, specularity and emissiveness. I wouldn’t expect to achieve it in a 2D drawing program, and I’m not sure what fraction of monitors can achieve it at all, but it’s simple enough in Unreal Engine.

In addition to teaching digital painting I also teach 3d. What you describe is completely correct and something I would emulate using Blenders BSDF shader. This would emulate real world materiality, but my point is that color is the lest of the key properties of a metal. For the most part, the Colour would derive from environment reflections, which would all be tinted with ‘gold color’.

> it’s simple enough in Unreal Engine The color of physical metallic gold is outside of sRGB color space. Maybe you could get close enough to fool people with some of the best modern HDR's (I don't know), but for most of the history of modern computing it didn't matter how good you were at digital animation -- no display could display the color "gold" even if you could mathematically compute the right color.

  It's just orange, reflective orange. The italics part is the rest of the owl.

  I'm not an expert on color profiles and HDR stuff but it seems like the kind of thing that's possible with PBR and the right color profiling, which isnt too modern. I'm sure that there are some colors in the human-visible range that aren't covered by sRGB but idk if gold is one of them

  sRGB is a red herring here. There are colors outside the sRGB gamut, but those colors are all very saturated. "Gold", including the color of the actual metal, isn't saturated enough to be among them. The real problem is that gold is a mirror. It's shiny and changes appearance based on viewing angle and environment. A computer can only simulate that for the scene within the computer. It can't make the image itself more or less shiny than the physical monitor. Without the shininess, gold just looks like a dirty yellow.

I wonder about things that can't be portrayed by our digital devices. Another one is the "speckles" you see when illuminating a surface with a laser.
