I called the manufacturer and got advice about coloring epoxy - you can
use the
universal tint colors supplied in paint stores. Just add enough to the
resin before
mixing to get the desired saturation. I used it for an inlay on the
top of a pedestal
for a statue. The veneer is Bubinga. It hasn't been finished yet,
when it is the
ring will be a solid smooth black. See it at
