A couple of colors look quite close to one another and even on my nails the difference is barely there. The formula on all of these were quite nice and very easy to work with. Great consistency too - the cremes especially were not too thick, and all colors level themselves out very well without any bubbling or cuticle pooling. Its a nice collection, but I do wish there were a couple of unique colors since I've seen these sort of colors from Barielle before. Paradise In The Tropics has got to be my favorite of the six!
