Idyllic is an inexpensive duochrome (multichrome?) from CQ. The polish flashes rust, bronze, and purple and it applied evenly in two coats. I picked it up at Rite Aid for around four dollars.
I probably should have posted this a month or two ago… it’s autumn in a bottle.
This swatch was photographed in artificial light. You don’t see much of the purple here; it’s more obvious in the sun.
