I did a colour test on some of the stampings I have a bunch of - some I like more than others - more transparent but overall they still look great. Of course it will vary with layers - and even thinning with some thinner to give a more transparent look on the metal. But its what I was looking for - have some dragonfly's and seahorses coming from panda hall for necklaces that I wanted to be able to colour- see my next post on updated color charts
Before and After
Used a base metal and coloured with a couple of colours - dries fast - I colour on wax paper for easy clean up. Hard to get a good pic of how really nice the colours come up on the metal.
