MAC Dash O' Spice Retro Matte Liquid Lipcolour ($21.00 for 0.17 fl. oz.) is a muted, light-medium brown with strong, yellow undertones that look almost green-tinged at times. The consistency was smooth, thin but not watery and spread well across the lips without leaving behind any streaking or unevenness. It had mostly opaque coverage (but I'd go back and add a little product here and there for complete coverage) that wore well for six and a half hours. The formula was somewhat drying to me.
