London-based beauty brand founder and makeup artist Joy Adenuga says she's "obsessed" with the OPV Beauty Rainbow Splash Palette (£29) and that's high praise indeed. "As the name suggests, the palette features all the colours of the rainbow," she says. "What I love about this palette is the mix of warm, cool, and neutral shades that include mattes, shimmer, and glitter, which darker skin tones can wear." Adenuga created the palette to create this beautiful shimmery blue and purple makeup look.
