From memory;
Flesh: Brown madder Alizarin, titanium white with hints of sap green+blue black
Highlights are more white and mars yellow[ or similar] to the base. I work the shadows onto the above that's already dried at 50oC in the oven. The shadows can be any combination of blue black and raw umber with sometimes a bit of sap green or purple alizarin if a warmer effect is needed. I warm up the cheeks, nose and ears with Indian red in poppy oil, ie. a glaze.
The blue was again, blue black with some raw umber and titanium white. You'll need to play around with these to get the strength of colour you want. Shading is by adding more blue black and raw umber to the base on the pad and taking to the model. Highlights would be more white with a touch of Mars yellow to stop it looking too 'chalky'.
