The undercoat was Tamiya Matt Black and the colours were constructed from Jo Sonja's and Atelier.
These are my favourite for painting horses as they have a totally different texture, transparency and sheen. The Raw Dark Sienna went over the Indian Red Oxide to create the chestnuts. The painting was mainly brushing and dry brushing, the latter being sometimes unintentional due to the heat and lack of air-conditioning in my studio.
This book by Caroline Silver I use for inspiration, although I do use other sources, including photos of real horses I came across on the Internet. The book is about horses, not painting horses.
