Here are swatches of OPI's Nice Stems collection (Seems like I'm working backwards - I got the Miss Universe collections before Nice Stems)
Play the Peonies (We’d put our money on this lovely soft-pink) is a frosty soft/pale pink.
Come to Poppy (Surrender to shine with this shimmering coral-pink)is a frosty pinkish/coral color.
Be a Dahlia Won’t You? (Give the gift of fabulous fuchsia—to yourself!) looks like a hot pink shimmer to me. (I guess it could be fuchsia... It looks a little dark in the pic - I will post more later)
I Lily Love You (Fall head over heels with this light pink sparkle) is a light pink jelly base with holo flakies, round glitter and square glitter.
