Transparent Emissive that Shows Texture ?

I need to make the rings of chain armor glow with emissive of selectable colors yet also allow the gray color of the metal to show through. Is that possible and can someone show me where to learn that? Thanks.

UPDATE: I figured it out. A simple way is to MultiplyAdd the two together. It makes both emissive, so it’s important to mask the parts of the texture the same as the emissive.
