Yes! Another rare modern pigment made into oil paint by David Coles, unique I think to Langridge.
In masstone a very dark blue, it is transparent which is generally preferable in colour mixing.
A relatively strong tinter providing a wide range of tints with white added. The tints bring out it's red leaning nature displayed in the violet edge to the blue tints. They range from lovely deep summer sky blues to gentle lilacs. The drawdown swatch opposite is pretty accurate.
It would make a great chromatic black when mixed with a transparent complementary colour and from that you could derive some really good greys.
It is like a modern Indigo but with more punch and lightfastness. Buttery consistency.
