For most of this painting, I used Cobalt blue to make the different shades of violet, but have changed now to using more of the ultramarine blue, which does not make it as 'grainy'.
My usual compositional technique of having a stable triangle embedded in the painting is not as obvious with this work. At the moment, it has a strong diagonal emphasis with the band of flowers from the bottom right to the top left. I expect that this will be counterbalanced once the cup and saucer are painted in, as it will 'draw the eye' of the viewer.
