Watercolour paint works just as well even when the colours are mostly black and white as in this portrait of a young cat here.
The soft white fur and huge blue eyes of Archie the cat here were a pleasure to paint. Watercolour is great for painting cat's eyes and the eyes are often the starting point for most of my portraits. Getting the reflection and depth in the eyes bring the portrait to life.
Watercolour always shows off the colouring at its best in cats, especially when the fur is so varied. Cats eyes are great to paint too, and is often what makes a portrait some alive at the end.
