Building your palette
A traditional palette comprises a warm and cool version of the primary colours, together with any additional colours that supplement mixing. In general, try not to overload your palette with too many semi-transparent or opaque colours, since these won’t lend themselves well to mixing and layering. For more intense colours, transparent and staining colours will make up most of your palette. For a dull palette, earthier staples such as burnt sienna, indigo and sepia will be prevalent, but expect to dilute to avoid muddiness.
