H&M Wintersky is like the winter sky at twilight, a mix of silver, pale blue, pale pink and darker blue. It is really a multi chrome, i.e. it flashes different colours depending on the direction of the light and the direction you are looking at it. It is also unique in my stash, and at around £2 is a must have in my book.
On to the swatches, all are three coats (multichromes are often quite hard to get opaque), with Poshe fast drying base coat and top coat, in natural light.
