Tart & Trendy ($15.00 for 0.10 oz.) is described as a "bright neutral orange cream [with a Lustre finish]." It's a brightened, medium orange with a luminous finish and warm, slightly yellow undertones.
I have a medium/ olive skintone with yellow undertones. My lips are slightly darker.
On me, this colour was the best. It's a beautiful coral and perfect to wear daily. Out of the colours I bought from the MAC All about orange collection (Razzledazzler, Sushi Kiss, Flamingo and Tangerine dream). This was one of my favourites. Highly recommend it!
