Grey and brown mixtures

Artists' Techniques

The artist used a range of mixtures to create varied shades of grey. A pale grey consisting of lead white with traces of a copper-based compound, likely azurite, is used to paint the rabbit. A darker grey created by adding vermilion to the mixture is used for the darker rabbit and the grey stag and its pair in lower margin. A blend of lead white, traces of azurite and vermilion, and the further addition of an earth pigment, is used to create the brown pelts of the stags and does in the lower margin, while two more grey mixtures are found in the ox (lead white, with traces of azurite and possibly indigo), and in the figure of the huntsman (lead white and ultramarine, likely ash) (hotspot 4).
