[Iris flower ink, clover leaf ink, Italian manganese purple, Australian yellow ochre, walnut ink on traditional gesso on 640gsm archival paper]
 
Before the mid 1700s, green pigments were hard to come by with most artists laying yellow over blue to make green. However when in season, artists made a pigment called ‘Lilygreen’ using the purple iris which was ground in a mortar and fermented for 5 days before adding alum.
