Visit the National Gallery’s Scientific Department to see how the blue and red pigments traditionally mixed to make purple paint are analyzed and identified. The methods used range from state-of-the-art electron microscopy to recreating historic methods for obtaining pigments. This film accompanies the National Gallery 2014 exhibition ‘Making Color.’
