Russian Blue is a subdued, deep, bluish gray with cooler undertones and a matte finish. The texture felt firmer in the pan, but it still yielded nearly opaque pigmentation in one layer. In practice, I felt like it worked well as it was the type of shade I apply less of and gradually build up (to avoid having to blend ferociously at the end). The eyeshadow wore well for eight and a half hours on me.
