MAC Omega is a slightly warm-toned, very light taupe with a matte finish. It is a limited edition eyeshadow that retails for $17.00 and contains 0.05 oz.
MAC Omega Eyeshadow ($18.00 for 0.05 oz.) is a a darker, dirty beige with neutral, olive-leaning undertones and a matte finish. The eyeshadow had opaque pigmentation in a single layer, which applied evenly to bare skin and blended out with ease. The texture was smooth, almost creamy with good substance to it, so it wasn't prone to sheering out to nothing when applied over bare skin. It wore nicely for eight hours before fading a bit.
