This week's theme is duochrome, and I have a great one to show you alright. Even though it's technically multichrome, but as everyone who got their misuse of a word pointed out to them has ever said: "Semantics!"
Two coats with top coat. This shifts so beautifully, but it can be hard to catch that on camera sometimes. Also, this wasn't really 100% opaque, because the base seems to be clear and just filled with colored, multichromatic flecks.
