At one angle it's violet with blue shimmer.
I wanted to try some water marbling, and I had this idea for just two colors. This is LA Colors Art Deco Black + clear.
Erm, I didn't really like the result. Other than the thumb, I find it too black shatter. But look, glowy purple! It's a bit soft-looking, just like in real life. Too bad WnW discontinued this shade.
