From what I was told at my MAC Pro store, they are for the eyes. I only got Deeply Dashing and have used it two times as just a single all over eye color and I have not had any problems. I know Temptalia gave them an F, but the one I have has worked great on me. I did use Painterly as my base, then used Deeply Dashing all over the lid. I also plan on using it as a contour shade for one of my client's performances in early October. She's into dramatic over the top makeup looks, so I know I can make it work. I definitely wouldn't use the pressed pigments as highlighters for every day use, though, or even outside of a shoot or performance, for that matter. I could get one of the lighter shades and try it out, but I feel like, if used as highlighter, you'll end up looking like you just came out of Studio 54.
