Experiment with colours

Each colour we’ve added has been done with separate Adjustment Layers. The beauty of using Adjustment Layers is that they give us all the advantages of working with a normal layer, so we can reduce layer opacity to tone the effect down, experiment with different Blend Modes, or use a mask to restrict it to certain areas. What’s more, we can change the colour or tonal settings at any time by doubleclicking the layer thumbnail, so we’re free to choose new colours for our makeup even after we’ve applied it.
