Colours are the first thing anyone notices when they look at a page. They’re also very easy to get wrong.

Just like drawing, I’m NOT going to teach you how to colour. What I WILL do, is show you the tools and techniques you can use to maximize what you can get from your colours.

Colouring Terminology

Hue vs Saturation vs Luminosity (video) - Bruce Gabrielle


  • Hue: The actual colour itself. Going from red to blue is a change in hue.

  • Saturation: How much gray is in the colour. The higher the saturation, the more “pure” and intense the colour. A saturation of zero is completely greytone.

  • Brightness/Luminosity: Related to saturation, but about how bright the colour is. A brightness of zero is black.

  • Flats: Single colours with no rendering. Done in advance of rendering to speed up the process (see the section on flatting) but can also be used stylistically in the final art.

  • Rendering: Varying hue, saturation and brightness to add more detail to colours.

  • Colour Hold: Changing black line art to a non black color. Often used for style but can also be used to show atmospheric perspective (more on that later).
