According to the benevolent AI this is how you can mix-up the gunmetal color:
"Mixing black and silver paint or ink generally results in a dark grey or charcoal metallic color. The black tones down the brightness of the silver, resulting in a deeper,Gunmetal-like metallic shade, or a darker version of the original metallic sheen depending on the ratio of black used.
- A deeper, darker metallic grey, commonly referred to as "gunmetal" or charcoal grey.
- Effect on Luster: While black deepens the color, it can sometimes mask the brightness of the silver, reducing its sheen if too much is added.
- Usage: Often used to create shadows or to create a more subdued, metallic look in painting or design projects.
For a lighter, brighter metallic finish, you would typically add white to the silver rather than black."
