Here are some great alternative to some of the higher end pigments! Great pigmentation, lots and lots of colors to choose from, long wearing if you add a base, overall good buy. The one ounce jars are 5 dollars, but you can also get the large sample bags which will last quite a while. (those are only a dollar each.)
Here are the swatches! I have Gold Sparks, Blackstar Blue, Chameleon, Coral and Sunstone.

Defiantly give these a try! Even if you just get the samples, there's so many colors to experiment with. Hope this was helpful!
