MAC RiRi Boy Lipstick ($15.00 for 0.10 oz.) is described as a “matte vivid lavender” with a “Retro Matte” finish. It is a medium-dark, pink-purple with a matte finish. MAC Heroine is darker, purpler. MAC Seasoned Plum is darker, less pink. MAC Up the Amp is glossier, so it appears a bit lighter, less intense when the two are swatched side-by-side, but applied, I couldn’t tell the difference aside from the finish.
