I love gold shadows. I like complex colors. I love me some duo chromes. Old Gold gives me all three!
Old Gold is a loose pigment, so it can get a bit messy. It works best with some sort of mixing medium. (I use a bit of Fix+ to wet my brush). It wears nicely with a primer.
Old Gold is an dark, antiquey gold with green duo chrome. Applied dry, it creates a nice wash of color. Used wet, it really comes to life.
