I tried the hint of mixing Quinacridone Magenta (W&N Permanent Magenta) with Phthalo Blue (Green Shade), and did indeed come out with something that looks very much like Indanthrone Blue! It was just a bit dilute because of all the water I added in order to rehydrate both of my paints, but if I didn’t skimp on it, I could probably make a full-strength mix.
I also painted out some Prussian Blue, which…I really like. I know it’s safe under normal circumstances, so maybe I can carry that knowledge with me. I’ve also decided to re-add Aureolin to my palette, though it doesn’t show in the image below (Trial 4):
…This is because I feel it might be useful in color mixing — particularly with cool greens — though it can’t really compete at all with Hansa Yellow for tinting strength. I would put Aureolin between the lightest yellow (Hansa) and Sap Green. I’ve also removed three colors (Cadmium Red Pale Hue, Winsor Orange, Cadmium Yellow Hue) due to multiple factors, varying with each paint.
The Hues are both Cotman (student grade) paints — from 2009 or before — and if I’m recalling correctly, they’re fugitive (though I haven’t verified that). Winsor Orange just tends to dull mixes, and I don’t need it if I’ve got Cadmium Orange Hue (a much more recent formulation [2016, I’m thinking] which may be less fugitive than the 2009 version [known fugitive], though I haven’t checked my memory against sources) in Cotmans.
This gives me six empty pans to work with (if I fill one with Aureolin)…
Anyhow, the Prussian Blue is really pretty (especially combined with Phthalo Green [Blue Shade]), and I’m trying to figure out whether to purchase the professional-grade paint. I know for a fact that the Cotman Prussian Blue (from 2009) doesn’t flow very well, but that’s to be expected of Cotmans — they’re really inexpensive.
I should get to bed sooner than later, but I wanted also to mention Cerulean. I have a Cerulean Hue, which I’m not too fond of. The only reason I mention it is that I’m not sure if I’ll need it for greens — I have Cobalt Blue, already, though. I’ve just been reading on handprint.com…maybe a Cobalt Turquoise could help and not be too similar to the Blue…or I could just swap the Turquoise for the Blue.
Cripes. Okay. I’ve just decided what I’m going to get. Prussian Blue and Cerulean Genuine. Tomorrow. Okay, brain?
I’m going to bed.
