On the left side of Dynamic Duo 4, there is a light-medium pink with a satiny sheen and barely-there blue undertones. This had pretty mediocre color payoff–I had to layer four or five times to get it to even show up. MAC Miss Piggy was very similar in color and in quality. MAC Feather Pink is a bit darker and bluer. On the right side, there is a deep, dark purple with neutral undertones and a matte finish. It has decent to good color payoff, but it is a bit dry in texture. MAC Indigo Noir is bluer. Urban Decay Rockstar is a tough lighter, red-toned, and has a shimmery finish. MAC Indian Ink is very similar but darker.
