Hi there,I fired this on a contour fuse on to black and it came out a pretty silver blue, but the transmitted red is completely absent apart from a very faint tint where the dichro wasn't on the black. How can I get it to show both colours? It's a bit disappointing

Hello

To see the transmitted colour you need to be able to see light through the glass, firing dichroic colours on black will make the transmitted colour not visable. 

Did you find what you were looking for?
