This was a limited palette painting, working with a No 4 Ivory flat brush. For fiddly bits (chiefly eyes) I turned the brush and used the corners to get a touch of detail. Whiskers were painted separately when everything else was dry using an extra long liner with about 2 hairs (I think it is aimed at miniaturists, size 30/0).
The palette was chosen almost by accident, as the support had seen two previous 'wipers' and as a result was coloured a sort of pale, salmon pink. It reminded me of the paler colouring on some beagle-type dogs and I thought it would be fun to try and make a dog emerge organically out of the mush of previous failures.
To paint his eyes I cleaned up eye-shaped holes in the background using cotton buds and mineral spirits. I seem to get a better shine on eyes if the background behind the transparent paint is white.
So, colours were: Transparent Oxide Brown (by Rembrandt - for the eyes); Burnt Sienna, Purple Lake, Lamp Black, Titanium White and Cadmium Red Medium (all Winsor and Newton).
