Apply colour to my character
After I’m done with black and white, I add colours on top. I create a new layer and lock it to the black and white layer (press Alt and move your cursor towards the middle of both layers until the cursor changes to the lock icon). I change the layer mode to Multiply and add bright colours, because the Multiply layer will dull down the colours.
Finishing details and texture
After this step I usually merge all the Multiply layers and the black and white layer into a single layer to work on. Don’t forget to always back up your layers, though. On the single layer, I begin to paint again, adding some textures and details with a custom oil brush.
