Watercolor Warm-Cool Mixing Chart

Here are my twelve QoR watercolor pigments used for mixing up all the colors I need. PV49 (cobalt violet) is an incredibly transparent, weak glazing color; it was not included, despite being on my palette.

These are all my possible warm x cool mixes (I've thrown cool yellows and cool red/magentas into the warm category). Nothing's a perfect mixing complement, but a couple 2-pigment glazes come pretty close. However, I have no problem getting very dark near-blacks combining various recipes of three pigments on this chart. I really enjoy playing with color and reading about all the geeky stuff behind our perception of it

In each square on the chart, I've made a wet-in-wet mix of the two colors by charging the cooler (blue/green) color into the warm color on the left side. The top right overlapping pigment squares show how the cooler color appears glazed over the warm color; the bottom right overlapping pigment squares show how the warmer color appears glazed over the cooler (blue/green) color.

I have listed each pigment's opacity (SO=semi-opaque, ST=semi-transparent, T=transparent) / staining (S=staining, SS=semi-staining, NS=non-staining) / granulation (G=granulates, - = none).

8 Warms (cool yellow through violet-magenta):

PY184 Bismuth vanadate yellow -- S/SS/-
PY150 Nickel azo yellow -- T/S/-
PY83 Diarylide yellow -- SO/NS/-
PR101 Transparent red oxide -- T/S/G
PR255 Pyrrole red light (pyrrole scarlet) -- SO/SS/-
PV19 Quinacridone red -- T/S/-
PR122 Quinacridone magenta -- T/S/-
PV19 Quinacridone violet -- T/S/-

4 Cools (purplish-blues through green):
PB29 Ultramarine blue -- ST/SS/G
PB36:1 Cerulean blue, chromium -- SO/NS/G
PG50 Cobalt teal -- SO/SS/G
PG7 Phthalo green, blue shade -- T/S/-

Hope this chart helps you find your own favorite combos!
