I like the contrasting colors. The winning factor? NO FALLOUT! What?! You heard me. Unlike many other cheap drugstore shadows, I've not had any fallout with the Color Icon line. <3
The blue looks a little more turquoise when applied to lids. The purple-pink is gorgeous; it causes a croma-shift/chameleon-effect.
Don't bother using the little brush and applicator that comes with these ... just go ahead and toss those. You'll need a nice shadow brush and, preferably, a crease brush to really push the pigments into your skin. You'll also need a primer if you want these colors to last. Creasing is a bit of a problem with these, but hey, they're $4 so I'm not complainin'.
Overall: cheap price-tag, beautiful colors, no fallout ... with a little primer, these are a keeper.
