MAC Neon Orange is a very warm-toned, medium-dark orange with a natural finish. It is a permanent lipstick that retails for $20.00 and contains 0.1 oz.
Neon Orange ($15.00 for 0.10 oz.) is described as a "bright clean orange [with an Amplified finish]." It's a bold, medium orange with strong, warm red undertones and a natural sheen. It had full, opaque color coverage, and it was lightly creamy. This shade is permanent at PRO stores (and regular customers now have access to the majority of the PRO range online). I've had this on for nearly four hours, and it's still going strong. Shades like Maybelline Orange Edge, Maybelline Vibrant Mandarin, MAC Good to Go, MAC Morange, and OCC Psycho are all rather comparable to each other. Shades like Maybelline Electric Orange, MAC Booyah, and MAC Fashion Nomad are a bit lighter, less reddened. Then, shades like MAC Scarlet ibis and MAC Sail La Vie are slightly redder and appear a bit darker. See comparison swatches.
