Yes, all of these shades are from MAC. I really believe that MAC does the best neutrals. They have a HUGE range of shades, finishes, and tones.
L-R: Orb, Wedge, Soft Brown, Texture, Cork, & Espresso
I know what you are thinking, these all look very warm. Perhaps, but bringing warmth to the eyes really brightens the eye area. Plus, my philosophy is like that of Bobbi Brown: all skin tones naturally have warm tones in them, so warm colors are very complementary.
My absolute favorite for myself is Texture. This shade works wonders for medium-dark skin tones and also looks great on mature skin (especially auntie types). I highly recommend all these shades, whether or not you use them for blending.
Do you use and love any of these? What is your favorite blending shadow?
