Urban Decay Flashback is a slightly warm-toned, dark lavender with a sparkle finish. It is a limited edition eyeshadow that retails for $19.00 and contains 0.05 oz.
Flashback is described as a "bright deep purple with pink sparkle." It's a meidum, violet purple with a soft, frosted finish. It had good color payoff with a slightly dry, but not powdery, consistency that could be helped by usage of a primer, as it didn't go on as evenly on bare skin. It started to crease after seven and a half hours of wear. MAC Sexy PB&J (LE, $17.00) is darker (95% similar). Illamasqua Trance (LE, ) is less shimmery, darker (90% similar).
