M. Graham has seven beautifully pigmented violets from warms to cools, starting with a Ultramarine pink, a subtle color of hyacinth in summer, or you can choose Ultramarine Violet for a very deep granulating blue-violet. For blues you have eleven hues. When you need strength in your hue try some that will give you a staining quality like Anthraquinone Blue or perhaps Prussian Blue or Manganese Blue, or if your looking for a vivid, high key, cool blue green try M. Graham Cobalt Teal.
