This pigment is the same as ultramarine blue red shade except for two differences. The colour is less red and the tinting strength is a little weaker. The green shade ultramarine blue is not a greeny-blue but is only less red than the standard red shade. For most practical uses of ultramarine blue, the red shade is preferable, but we have continued to make this green shade because the colour on its own is very attractive as it affords a more mid-blue. For some painters this will perform better.
