Don't Tell a Sol is a bright, opaque yellow crème nail lacquer from OPI's Spring 2020 Mexico City collection, named as a play on "sol," Spanish for sun. It's a warm, saturated yellow rather than a pastel, formulated to build to full coverage in two coats — a genuine point of difference, since yellow pigments are among the more streak-prone shades in nail lacquer generally. Apply over a base coat and finish with top coat for a glossy manicure that holds up to about a week before chipping.
