Ivory is a pale, cool-toned white with a matte finish. This shade is part of the permanent range (and has been in a lot of Bobbi Brown's palettes, too). It had fairly good color payoff, and the texture was soft, slightly powdery, but blendable. Here are several see comparison swatches for white eyeshadows.
This silky, matte powder shadow goes on smoothly & blends easily. The densely pigmented formula can be layered and comes in a range of beautiful shades for defining lids and lining eyes. (You can even use it to define your brows.) Comes in a sleek, flip-top compact that can be used individually or popped into an empty Palette (sold separately).
