Lady Muck is a soft blue-grey with a slight pearly finish and a superfine silver shimmer. The colour reminds me of the sky over the ocean on an overcast day. It is very similar to China Glaze Sea Spray, but deeper and with the silver shimmer. I have seen swatch photos where Lady Muck looks like it has a much brighter blue base, but for me this is a very subdued, muted blue.
Have you ever had a "Lady Muck" product? (i.e. something that looked fancy and awesome but disappointed you)
