Divine Rule is described as a "frosty grey mauve with silver pearl [with a Lustre finish]." It's a warm-toned, taupe brown with a frosted sheen. It had a light sparkle, but it was less sparkly compared to the other two Lustre shades in the palette. It had better color payoff, though, and it was more in line with how the formula is supposed to be. See swatches of all dupes / view dupes side-by-side.
