MAC Sunbasque is a moderately warm-toned, light-medium copper with a frost finish. It is a permanent blush that retails for $24.00 and contains 0.21 oz.
MAC Sunbasque Powder Blush ($24.00 for 0.21 oz.) is a medium copper with warm, rusty undertones and fine, gold and copper pearl. It had semi-sheer (as expected, based on the "Sheertone Shimmer" finish), buildable pigmentation--up to semi-opaque in three layers--with a drier, dustier texture that didn't feel particularly promising by touch, but it applied better than anticipated! I remember it being smoother years ago, but memories get fuzzy when a decade passes (I think Sunbasque might have been my second blush purchase, pre-blog era!). The blush applied evenly to bare skin, blended out effortlessly, and sat well on my skin without emphasizing my skin's texture but still producing a noticeable sheen--more shine than overt shimmer. It wore well for eight and a half hours on me before fading slightly.
