MAC Call of the Canyon Eyeshadow Quad ($33.00 for 0.19 oz.) includes four shades of warmer, neutral tones. All four are new and limited edition to this quad. Overall, the palette was pretty easy to use to create a cohesive look out of, with the darkest shade being the weakest as it had a duster, sheerer texture. Only one shade was really good, though, and they are more dupable shades (except the darkest one), so there are better-performing options out there.
