No, not all of the shades are matte. The matte ones are violet ink, espresso bean, truffle, fresco, vanilla nuts, plum smoke. The shimmers are sparkling dew, guava, African violet, kir royal, bamboo, and primrose.
Hope this helps!
Vanilla Nuts, Plum Smoke, Violet Ink, Espresso Bean, Truffle, and Fresco are all matte colors.
African Violet and Bamboo are Luster. Primrose, Guava, Kir Royal, Sparkling Dew are Sateen.
Half are matte, half are shimmer. The matte shades are Plum Smoke, Violet Ink, Vanilla Nuts, Fresco, Truffle and Espresso Bean.
Guava and Primrose have a light shimmer to them. African Violet and Bamboo have a little more shimmer.
6 of the colors are matte. The colors are vanilla nuts, fresco, plum smoke, truffle, violet ink, and espresso bean. Violet ink and espresso bean, in my opinion, look darker in real life compared to the picture.
