Plain, it is a nice, translucent orchid purple. Encased in clear, it lightens a little but seems to become even more translucent. The edge between where the encasing stops and the core starts is slightly blurred. With plum encased over a clear core, the translucency is magnified but the color remains darker.
Silver foil just disappears when just melted into this, but when it is reduced and encased in clear it gives that pearly lavender lustre that I like. Copper leaf looks better than I have come to expect and is a combination that I will probably use again. I only tested DH aurae with plum but was very happy with the bead I made, a base bead of plum with dots of aurae encased with bumps of clear.
CiM tuxedo looks good on plum, remaining crisper than I expected. The dots of plum on top of the tuxedo half of this bead did disappear. Psyche didn't reduce well on the next bead, but I am beginning to think I pulled a stringer of dark amethyst or Effetre black (which I didn't think I had) because none of the beads I have made with this stringer have reduced. Plum silver looks better on the middle bead than the picture shows. The metallic effect stays near the edges and the center has a bit of a line down it on the plum silver scrolls, but I would not be afraid to do this again. Copper green looks nice against the soft plum, but unless something very subtle is desired, there's no point in putting the plum on top of the copper green. EDP looks a bit weird, making the plum underneath look redder than it would be. I wonder what Effetre Sedona would look like with the plum? It seems they are almost the same shade.
Definitely worth a second purchase.
