Donna, Dioxazine Purple is one of those lovely transparent colors that you can’t mix. You might try experimenting with a little ultramarine blue and alizarin crimson for a substitute, but it wouldn’t have the same punch that dioxazine has.

I wouldn’t be without it.

I’ve enjoyed ultramarine violet as a transparent purple. It won’t be nearly as intense as the dioxazine, though, and probably a bit cooler. Grumbacher sells a tube for cheap.

Donna,

Thanks Nancy!

I’ve made a promise to myself to stop buying art supplies!
[COLOR=”red]Frugal but not as much fun.[/COLOR]
I have things I don’t know how to use and color has been a challenge. To that end I am trying to work with a limited pallet in hopes I can learn more about mixing.
[COLOR=”red]Lots of help here and in the Color Theory/mixing forum also.[/COLOR]
It’s a luscious color.

Oh well, I may have to give in.
[COLOR=”Red]I can relate to that.[/COLOR]

You need to learn for yourself what pigments do, not rely on formulas.

Quoted for emphasis…

Donna, there is no one magic formula- in fact you can mix just about anything from a basic palette. People often use different pigments and end up at the same (or extremely similar) result. It’s just a matter of knowing how pigments interact. That’s why you can ask for skin tone recipes and get 20 different answers… all of which work.

Honestly I think you can do this painting with a good basic red (Like cad red medium or equivalent OR maybe even an earth red like venetian red)), yellow ochre, french ultramarine, burnt umber, and a black. (And Titanium white)

D. purple is a marvelous color and I would never discourage anyone from getting it because it is an awesome color (and i do not, as a rule, ever discourage people from buying paint :p) but my recommendation would be to use colors you already have and see what happens.

Here is some information I found about Dioxanine purple from Dick Blick site. (I really like them)… I am trying to match my colours up with the material list provided, on a course I am taking on realistic portrait painting… Here’s hoping.

Here is the info I got:
Gamblin Artist’s Oil Colors
00401-6023 — Dioxazine Purple

This color contains the following pigments:

PV23—Dioxazine Violet

Pigment Type
organic
Chemical Name
carbazole dioxazine
Chemical Formula
C34H22Cl2N4O2
Properties
Dioxazine Violet is transparent and has very high tinting strength. It is a staining pigment, very dark valued when it is used at full strength. Concentrated, it paints out nearly black, but it mixes with Titanium White to form bright, opaque tints of purple. PV23 produces slightly redder shades than PV37. Because the hue can vary with the conditions of preparation and grinding, it may be offered in red shade, blue shade, and so forth.
Permanence
Dioxazine Violet has good lightfastness. There may be some concern about it fading or shifting in color in tints and washes. Some artists have reported that PV37, a molecular variant, is more lightfast than PV23.
Toxicity
n/a
History
Two molecular variants of Dioxazine Violet, PV23 and PV37, are available. They have similar properties, but mix slightly differently.
Alternate Names
Dioxazine Purple, Chromothal Violet, Mauve, Carbazole Violet.

Happy Painting.
Joy
