I intentionally did not use the combination of Yellow and Ultramarine Blue.
The grayed green color hue obtained from this double opaque mix would
add a third color to this painting, but that wasn't the exercise.
This is the deep end of Yellow ( brown ) and the in-between ochers/oxides mixing with Blue
Yellow is the undertone of brown as with the
water color pigment of old,
Burnt Beechwood and the crystals WAVELLITE and VESUVIANITE plus many others.
It takes two transparent oppositions to mix neutral-dark colors,
or one transparent and one translucent color.
Two translucent colors, or one transparent and one opaque color.
Two opaque colors just won't do it.
Top-tone is adding White to the color.
Under-tone is adding clear.
Mass-tone is thick out of the tube.
Transparent is clear like colored glass.
Translucent is floating colloidal compounds of colored elements.
Milk is translucent.
Opaque is dense and light blocking, like a rock.
YYYY = As Yellow as you can get,
MMMM = pure Magenta
MMCC = Ultramarine Blue
CCCC = Thalo Cyan Blue
These are the colors to mix to make a neutral dark (like the underside of a cloud)
from Blue and Yellow (Yellow transparent or brown) pigments.

|WAVELLITE, Al3[PO4]2[OH,F]3.5H2O, H3.5, SG-2.36, orthorhombic crystal system,
acicular, like the needles of Rutile suspended in clear crystal, only these needle crystals form a dense rocklike mass.
ALUMINUM, yellow, brown, blue, centering standard, transparent. Aluminum really does it big this time, each needle starts at the center radiating outward, concentrically ringed bands form around the center, each band ending as a cleavage line, twenty or so bands per complete needle crystal. The band itself can change from clear transparent to opaque white while in the center, the second band range is transparent yellow crystal, than brown, than blue. From brown to blue, the crystal can change into an aggregate and lose it's crystal properties.
THIS MINERAL PHOSPHATE SHOWS A DARK CENTERING OF YELLOW TO BROWN AND BROWN TO BLUE. The Crystal Color Wheel matches this Real Color Wheel.
The Red, Yellow and Blue color wheel is still being taught to every school and every age group except in New York State where they changed the state's art curriculum. 2005
The Yellow to Blue opposition is the same opposition as the Brown to Blue opposion, following the yellow oxide to brown oxide scale of colors. Brown is just the deep end of Yellow. Here is a painting using the properties of a bright yellow opaque pigment and opaque blue to make a dull green.
Look at this perfect color opposition of Yellow/Blue and Yellow-green/Purple.
The colors highest in chroma and intensity in the painting. I was driving to Hana during a storm when I came to this waterfall. I have an extended sun blocker on the van which also keeps the rain off my windshield. That's a lot of water coming over the falls, I'd never seen it pumping so much. "Paint the bird before it flies away" so I stopped and painted a water color.
