MAC Seaside Cream Colour Base ($17.00 for 0.12 oz.) is described as a “soft peach rose.” It has a very warm, slightly bronzed look to it with a hint of peach–the rose is very, very subtle. I can see some using this as a highlighter, and I think it will work particularly well on darker skin tones as such. It has more of a sheen than shimmer to its finish, and it can easily be blended out for a glowy sheen on cheeks. It’s rosier than MAC Peachtwist but has a lot more shimmer than Burberry Russet.
