Opaque or transparent? Are you trying to let another color show through or trying to just darken the dorsal side of something?
- Opaque is easy.... dip in black then top coat with blue giltter/clear mix.
- Transparent gets tricky with certain colors. The actual grain size of certain color powder can been seen and gives the pixelated look sometimes.
I have made a transparent blue colored powder that had a few different glitter colors in it - tryin to match the Kalins Northern Bluegill color. The base that i started with was 15 parts clear to 1 part blue.
