Exercise 2 - Mid-intensity violets with orange-red and violet-blue. Cadmium scarlet and French Ultramarine.
Well, I don't see much improvement with these violets, maybe a little with the lighter washes. I'm working a new chart layout that works well with the scanner. Perhaps I could have got in a few more columns. Where I'm having difficulty is detecting the nuances in color while mixing the pure pigments. As the tones lighten out, I see the differences so much more.
So for me, it's not only an exercise in learning about pigment mixes but also the mechanics of mixing. Like how much water to include in the most saturated mix. How to gradually fade. How to mix subtle color differences. It's all practice for me.
