Ian starts the book by highlighting the importance of colour, and how the choice of colour can mean the success or failure of any project. He uses science to help describe what colour is and how it manifests itself. The main body of the book shows artists how to use a palette and how to organise yourself prior to mixing. Ian works through all primary, secondary and tertiary colours showing the range of options available and possible mixes. This book helps artists understand how to mix colours in different mediums and how colour can help to develop their work. Artworks illustrate how to put theory into practise. All of this makes this book suitable for all artists whether they are a beginner or a professional.
