Natasha Denona Sienna is a very warm-toned, medium-dark copper with a sparkle finish. It is a permanent eyeshadow that retails for $25.00 and contains 0.27 oz.
Natasha Denona Sienna Chroma Crystal Liquid Eyeshadow ($25.00 for 0.27 oz.) is a rich, golden bronze with warm undertones and a sparkling, metallic finish. It was intensely pigmented with a smooth, fluid consistency that was spreadable and felt lightweight on. I didn't have any issues applying it and diffusing the edges on my lid, though it was a bit thicker-looking upon dry down (I don't think it emphasized my lid texture much, if at all, like some shades in the range did). It lasted nicely for 12 hours without fading or creasing, but I'd caution one to avoid blending it out once the product dries down due to a tendency for it to flake away at that point.
