MAC Opera is a slightly cool-toned, medium-dark red with a cream finish. It is a limited edition lipgloss that retails for $19.00 and contains 0.1 oz.
MAC Opera Lipglass ($16.50 for 0.17 fl. oz.) is described as a "dark red." It's a deepened, blue-based red with a glossy shine. I swear there is a very, very fine shimmer that's barely-there. It had semi-opaque pigmentation--there was some translucency so the natural lip color comes through--that goes on evenly. This shade lasted for five hours. See comparison swatches / view dupes.
