I have seen swatches of these shades on other blogs, and they are not all true. You can see swatches of the six shades I purchased here; they are true to color. Maybe not works of art, but true.
If you really want a specific color, it's best that you go shopping for these lovelies at a counter. If you live in the DC area, I recommend you seek out Loyd Cassler at Saks Chevy Chase or Kathy Shoreman at Neiman Marcus Tysons. They will both help you select colors that will make you glam.
