MAC Thunderbolt is a moderately cool-toned, very dark gray with a sparkle finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
Thunderbolt is a dark, taupe-gray with subtle, cool undertones and warmer, gold shimmer. The shimmer seemed to pull away from the base color, which resulted in an uneven result. The base color was also on the dusty side, so everything appeared sheerer than intended once applied to the skin. It would be better with a lightly tacky or emollient base to give it something more to adhere to. On me, it lasted for six and a half hours before fading noticeably. Chanel Tisse Rhapsodie #4 (LE, ) is more shimmery (95% similar). Guerlain Crazy Paris #5 (LE, ) is less shimmery, lighter (90% similar). Burberry Storm Grey (No. 27) (DC, $29.00) is lighter (90% similar). Cle de Peau Satin Moon #4 (PiP, ) is less shimmery, darker, warmer (90% similar). Kevyn Aucoin Dark Chocolate (LE, ) is less shimmery, darker (90% similar). Natasha Denona Deep Slate Gray (32P) (PiP, $29.00) is more shimmery (90% similar). Disney by Sephora Midnight Hour #4 (LE, ) is more shimmery, darker (90% similar). See comparison swatches / view dupes side-by-side.
