I have a couple (Pearl, Black, etc.) that I use mostly on my eyes to make colors more vibrant. They're fairly emollient, so they don't dry like Paints and Shadesticks do and will crease on the eyes if applied too thickly. As such, I usually put on a Paint first, and then pat a very thin layer of the CCB on with a brush like the 242, then put shadow over it. It really helps with colors that you have a hard time getting to show up, but it can be tricky. HTH!
