Understanding blend modes
Usually, while drawing on a layer, you will notice that your strokes are appearing as opaque areas of digital “paint” obscuring the contents of any underlying layers. However, there are several ways to make layers “blend” and create different visual effects with each other. Blend modes allow you to choose how your layers interact. The layer on top that affects the layer below with its blend mode is called the blend layer. The layer below the blend layer is called the base layer.
The default blend mode is called Normal and is indicated by the letter N next to the layer name.
When you tap on N, you will see a menu open up under the layer. Aside from the layer opacity slider, it also lists all the blend modes available on Procreate. We will learn more about those in the following sections. They will be demonstrated by placing a block of magenta over the same illustration and applying different blend modes to it.
