Lucy is clear with very few air inclusions, and when worked it remains quite clear in normal lighting. Under uv lighting Lucy is a very intense hot pink! A very stable color to add to the uv pallet. Lucy works great on the surface and can also be worked under clear. Fantastic for blown and sculpted applications. My favorite use of Lucy, is layering it over all other colors to create unique blends! Thanks for the great new color Northstar!
