Tarte Solo is a very warm-toned, light brown with a satin finish. It is a bronzer.
Solo is a light-medium, yellowed brown with a subtle, satiny sheen. It had semi-opaque, buildable pigmentation that adhered fairly evenly to bare skin and blended out without too much trouble, but it wasn't as effortless as best-in-class bronzing powders (or some of the other shades in the palette). The bronzer lasted well for eight and a half hours on me before fading noticeably.
