A peach colour underpainting of Indian Yellow and Quinacrine Rose, with touches of Permanent Carmine, in bold sweeps. The blue of the Iris flowers seemingly beyond grasp. In my box of magic paints, Indigo Blue. (Van Dyk Ferrario No. 57) and Mineral Violet Deep (No 47) that touch of inspiration. 

For the foxgloves, I used a mixture of Alizarin Crimson (Winsor&Newton Artists) and Violet Rose Madder (Ferrario No 48)
