MAC Groundwork is a slightly warm-toned, light taupe with a pearl finish. It is a permanent eyeshadow that retails for $23.00 and contains 0.17 oz.
MAC Groundwork Pro Longwear Paint Pot ($23.00 for 0.17 oz.) is a light, taupe-brown with subtle, warm undertones and a mostly matte finish. It appeared grayish when applied as full coverage and warmer, more red-toned when applied as a sheerer wash of product.
The texture was smooth, lightly creamy without being too emollient but wasn't as thick or as dry as some of the matte shades in the range, which made it an easier shade to work with for all-over application where blending was needed. It had opaque color payoff that lasted well for 14 hours before fading a bit and 16 hours before creasing became visible.
