Six separate spaces that include three corresponding colours that are created to group the colours into similar groups (hopefully this makes sense), so a total of 18 colours. The colour trios are nice and the colours work great with each other, and the whole palette works together too. The shades are pigmented, blend well, and apply well, especially the more shimmery colours. The only drawbacks are that the colours do tend to blend together. The separate strips of colour are thin and it's actually pretty hard to pick them up on certain blending brushes. This is definitely a problem with the white, grey, and black space. Also, the packaging is awkwardly bulky and cubical; I feel it would have worked better in a rectangular package.
