This was a limited palette painting. Most of it was painted with Pthalo Blue, Alizarin Crimson, Transparent Oxide Brown and white. I obviously needed a bit of Cad Yellow for his tricolour gold flashes. I did those first, in fact, and worked for an hour or two on something else while the paint tacked up a smidgeon.
Tricolour dogs have an unfortunate habit of turning greenish and muddy if you are not paying due care and attention. I have had more tricolour dog wipers than any other subject, except perhaps for tabby cats - where the same problem applies. Through trial and error, especially error, I have found putting in the gold markings first and waiting a while is most likely to result in a painting without tears.
