This swatch is quite concentrated, but when blended out this provides a much more subtle shimmer that is not disco ball in effect at all. I've used it to highlight my eyes, cheekbones, and lips, all to good effect.
Here is Rose Gold blended over Tarte's LipSurgence in Perky. If you click on the photo to enlarge, you can better see the shimmer it provides.
