I have Hue. When I apply it directly to my lips, it just mutes their natural color a bit (they're very pigmented). It's a nice seminude lip.
When I want the color to be more opaque, I apply Hue over a light lipliner. For instance, I have Rimmel's Tiramisu, which is a midtone warm peachy color, and if I apply Hue over that, it looks warmer and makes a much more nude lip.
