Revlon Neptune Star is a slightly warm-toned, dark blue with a glitter finish. It is a limited edition eyeshadow that retails for $4.99 and contains 0.028 oz.
Revlon Neptune Star Diamond Lust Eyeshadow ($4.99 for 0.028 oz.) is a muted dark navy blue with multi-colored shimmer (preodminantly blue, green, and violet). The color payoff is sheer and looks almost muddied when it is applied dry, and when it's applied wet, the navy blue starts to bubble forth. Dry, it has a similar color as Dior Smoking Blue, though it doesn't have the same shimmer/glitter. Make Up For Ever #147 is closest in terms of overall color but lacks the glitter component.
