Really like this diagram. It’s very similar to the way I do makeup!
The light tan is the “highlight color. You can use a shimmer or sheen eyeshadow for this. The light color is the lid color, the darker grey is the crease color and the Black color is the accent color. Notice in this diagram there is black on the inner rim of the eye. An alternative to this is to use a white pencil to open the eye. I sometimes will skip the crease color and blend the accent color from the outside.
