While working on something for Fibre & Stitch yesterday, every time I finished with a colour I rubbed the brush over the torso, I was using Liquitex Interference Medium Opal, and Daler-Rowney Interference Medium Gold, most companies do their own range of interference colours.
the colours don't really show up in the photograph, but I thought I would give you a little look see anyway :)
