MAC Sketchbook is a moderately warm-toned, dark brown with a frost finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Sketchbook is described as a "glittery blackened olive [with a Lustre finish]." It's a dark, warm-toned olive brown with dirty gold sparkle and shimmer. It had a very stiff, dry texture that resulted in sheer, uneven color payoff. With a fluffy brush, I was able to get some color and blendability, but it's a rather poor shade when all was said and done. It does have a Lustre finish, so the sheerer color payoff isn't unexpected, but the dry, uneven application was. Dior Bonne Etoile #3 is less sparkly. MAC Gilt by Association is darker. Giorgio Armani #6 is less sparkly. See comparison swatches.
