This is a handmade watercolor that combines a few pigments  and a metallic pearlescent add- in in order to get the perfect shade. 
 
This color is  Donut Glaze Shimmer  and the shade is a beautiful shimmery purple color! The shimmer is a lovely silver. It would be perfect on butterflies, feathers, or anything that needs a pop of purple shimmer!  I am still learning how to photograph metallics and this one is more stunning in person!
 
I handmade and filled these containers so some natural settling and variation will occur.
