Steve Garner gives examples of how to create a range of tones.

Tone in design

How do you create depth and tone on paper? How do you create a cd case from scratch? Steve Garner, Professor of Design at The Open University answers these questions and others in this introduction to design basics. All design begins with translating ideas on to a canvas, and this collection encourages you to begin thinking about design principles from how letters are shaped to creating three dimensional models.
