Take control of your colouring
A. Get your layers organised first!
My layers are always organised by having a layer for each major element in my artwork. In this example I have a layer for my line-art at the top and a layer for the subsequent base colours of my character’s skin and hair. This means I have full control over editing each element separately.
B. Colouring the line-art
The next step is to enable the Lock Transparency function for my line-art layer, which gives me the option to colour just the outline of my character. Select the base colour of the skin and go slightly darker. Notice now as I paint the skin outlines, it gels the lines with the skin colour. I then repeat the process for the line-art of the eyes, lips and hair.
C. Add light and shadows to the base colours
For the final stage, I Lock Transparency for the base colour layers, take an airbrush and start rendering by shading in the tones. My main focus is to play with the edges of the base colours to reflect light and shadow. You can always go back into the line-art layer and adjust the colours to fit the tones.
