From Left to Right: Midnight, Golden Olive, Shell, Bare Bronze, Espresso, Flame. Midnight, Shell, and Espresso are all matte shades while Golden Olive, Bare Bronze, and Flame are shimmer shades. Espresso and Midnight are the most opaque of all the shades I have tried while Shell is the most sheer of the six shades.
