Mahogany Brown _ Schmincke PBr33

I recently bought a tube of the new Schmincke  Mahogany Brown which is PBr33 - Pigment Brown 33. This is Zinc Iron Oxide and is described by the Pigment Database as "Dark; brown to reddish Brown". Handprint say it is a very lightfast, very opaque, staining, very dark valued dull brown but then says ..."a handsome blackish brown'.....an interesting pigment" The only source of this pigment was previouy 'Schmincke' who called it Walnut Brown. This new colour replaces Walnut Brown and I have no idea what the differences are although, presumably, there are some. I have also included the 'new' Transparent Brown previously called 'Translucent Brown' which is PBr41. Again I've no idea what the differences are if any.

Mahogany Brown is top left with Transparent Brown 3rd from the left. I now use this instead of Burnt Sienna, although as I have stocks of the latter .....! Handprint says it works well with Ultramarine Blue so I've done some swatches with the colours side by side and others where I've mixed them together. The one of the bottom right granulates nicely and looks interesting. These samples are rough and ready so don't take them as gospel.

I gave a small blob of the Mahogany Brown to Yvonne Harry, the co-leader of Avon Valley Artists -  a superb artist particularly of flowers, her speciality,  and showed her the following work in progress of a young indian girl. Her immediate reaction was it looked like a useful shadow colour.

The brown areas are Mahogany Brown heavily diluted except for above the eyes, with Ultramarine added to create the darks.

Current price for both these colours from Jacksons is £9.50p for 15ml. I would like to do more reviews but as I get no free samples - I tell a lie I did get copies of Judy Whittons Venice book and Gerard Hendriks DVD due to their generosity- but thats all!
