Hello.
Sharing gold mixes (non metallic) as requested.
I have three mixes on my palette:
A dark one with burnt umber, mars brown and a touch of mars yellow
A basic one with a portion of the dark mix, some dark cadmium yellow and mars yellow
A light one with mars yellow (not much), dark cadmium yellow and Naples yellow.
Those mixes are spread next to each other on the braid surface, according to the level of illumination, and melted.
Extreme highlights are painted once the first coat is dry, with a mix of Naples yellow and titanium white.
