The duochromes like Helium arent that dupable so if you are looking for something a little more unique then any of the duochrome pigments might be great, but Helium itself isnt a great pigment, the colour is quite lovely BUT its chunky and messy and the best way to work with it is wet, it doesnt blend easily dry and can flake if you apply it too thickly. I have it and wouldnt buy it again.
