Sugar Dune is more pinkish compared to other nude pinks like Chanel Jade Rose, Tom Ford Toasted Sugar and Tom Ford Show Me The Pink.
Coral Beach is more of a straight peach compared to Chanel Distraction, Laura Mercier Cabana (discontinued) and NARS Vertebra (discontinued from the Pierre Hardy collection).
Incandescent is the perfect mix of copper, gold and rose. It's not too metallic on the hands which makes for a more neutralish shimmer. Below compared to Chanel Delight, MAC Soiree, Chanel Rose Moire and Marc Jacobs Le Charm.
Indiscretion proves to be a slightly deeper but brighter pink. Below compared to Tom Ford Trophy Wife, Chanel Pulsion, Chanel Rose Insolent and YSL Rose Babydoll.
I hope these comparisons help with your purchasing decisions!
