The base is a black, more of a jelly than a cream, with tiny blue and green glitter. Having both colors makes it a little more complex. Sometimes one color will flash and other times, both will. I can't stop staring at my nails because of it. I definitely think it's one you have to see in person to fully understand how beautiful it is.
I love how it looks on my nails! It's so much better than my swatch of Vampire's Blood, which I wore on much longer nails.
Witch's Brew might not be the most unique polish out there, but it's still very pretty. It was released last year for Halloween, so it might be harder to find in Icing stores but I've seen random bottles hanging around, so it doesn't hurt to look. Have a great weekend!
