3 Colouring in Photoshop
I choose the Magic Wand with a Tolerance of 22 per cent and select all the negative space in the drawing. I click Selection> Modify> Expand> by two pixels, and then Select> Inverse. Just the character is selected now. I create a new layer under the line work and fill the selection with a solid colour. I then use the Brush tool to colour in the different parts of the character.
