Nude Compliment (90) is a subtly, cool-toned taupe-brown with a metallic finish. It seemed like the top layer, where it reflects, is more cool-toned and grayer, while the base seemed warmer, more reddish.
So happy I was finally able to get this shadow. Like almost all the Colour Tattoo shadows, it wears like iron. The colour is lovely - it's very much like Tough as Taupe only with a bit of sheen, which I prefer since Tough as Taupe can look a bit dry and flat. It's a shame this shade isn't a permanent addition to the line.
