2 Propanol Chromasolv + Indigo and Gold acrylic paint.
because the paint has to be very wet and thin for the chromasolv to work well the support needs to be very thick. This technique shows promise in relation to the broken colour techniques in Vermeer’s Milkmaid
Should try this with indigo and gum arabic and yellow ochre and gum arabic with alcohol sprays…
