I saw there are different types of Phthalo Blue ( Green Shade, PB15:3) and Phthalo Blue (Red Shade, (P.B. 15:1).
I am using water mixable oils and Windsor Newton only do Phthalo Blue (Red Shade) in their range so I ordered this.
Will this do okay for mixing greens with lemon and cadmium yellows?
I started with ultramarine blue that I have and noticed the greens don't look right.
Was following this on Jackson's art.
