expanding the collection of colors (finally able to work a bit!)
I am expanding my color “gamut” by making “subtractive” pigment mixtures. Everything is “plotted” in a CIE u’v’ diagram (see below).
The blue dots are measured colors, the two red squares are very pure cadmium Reds, the green triangle and the light blue cross are my new best Blues (one being very very dark: 3% of light diffusion), the cross in the middle is the white point. The Orange dots represent the limits of the sRGB gamut – I’m getting very close!
I figured out that even my best mineral pigments can become better by “purification” using transparent organic pigments.
