Sky is a very light baby blue shade. It's not highly pigmented but helps to brighten up my eyes when I wear it.
This is a very light baby blue shade. The color is pretty but it has almost ni pigment and it applys streaky on me.
As the name implies, Sky is a very light baby blue (or sky blue) color, light enough for a highlighter color. I don't wear blue very often, but for those who do, this would be a nice color. Goes on very sheer with a tiny bit of shimmer.
