MAC On and On is a slightly warm-toned, dark plum with a glitter finish. It is a permanent lipstick that retails for $19.00 and contains 0.1 oz.
MAC On and On Lipstick ($17.00 for 0.10 oz.) is a medium-dark, reddish-brown with warm undertones and duochrome sparkle that shifted from green-gold to bluish-teal. It had semi-sheer to semi-opaque color payoff, but the consistency was fairly slippery, which resulted in patchier coverage and color that settled into lip lines. The color lasted for almost four hours, so that was an upside, but it just looked bad on its own. This is a deeper, more conventional base shade, so it would work well with a lot of lip liners for added coverage while still getting the uniqueness of the shimmer to come through.
