Frank is an experienced watercolourist. He demonstrated his technique on three different landscapes. He suggested there are three distinct steps to a successful painting: the first wash, then the mid-tones, then the drama of the darks and shadows. He always puts the same colours in the water as in the sky. His favourite colours ? cadmium yellow, red and orange, aqua, olive green, indigo and burnt sienna for a lovely grey, sepia, van dyke brown, alizarin crimson and ultramarine blue.
Letting the painting dry between the washes seems crucial also. When outside painting, Frank uses small pieces of paper stuck onto cardboard, often the backing from pads of paper.
