Review of MAC Frost - Humid by she_said_so
This is almost exactly like Green frost pigment. I got it and discovered the similarity and wanted to return it, but since Green Pigment is being discontinued I figured I might as well keep it.
It is every so slightly lighter than Green pigment - I'm finding that I actually prefer it. It's now my favourite dark green colour. It goes so well with Blue pigment and other greens to contour. Great versatile colour. If you missed out on Green pigment, this is a great substitute.
