Copper #3 is a light orange with warmer undertones and a satin finish. It had mostly opaque pigmentation with a soft, lightly powdery texture that applied evenly and blended out well. I found it was faster to fade than average, so I'd recommend using it with a primer underneath. It wore well for seven hours before fading visibly.
