Painting on Location
with the Real Color Wheel
Color Oppositions
YELLOW and BLUE
Ultramarine Blue deepens to a neutral shadow color by adding it's opposite color Yellow,
either a Transparent Indian Yellow Brown/Side or a Yellow that has already been deepened to a
Burnt Umber or Burnt Umber hue.

Yellow/Brown opposit Ult.Blue only.
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 ) 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 and many others.

Yellow is dark brown
It takes two transparent oppositions to mix neutral 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 "basic color wheel" ( Red, Yellow and Blue primaries ) is still being taught to every school and every age group except in New York State where they changed their state's art curriculum. 


The Yellow to Blue opposition is the same opposition as the Brown to Blue opposion,
just different adjustments of Yellow.
Brown  is just the deep end of Yellow
Here is a painting using the properties bright Yellow opaque pigment and opaque Blue to make Green.


Look at this perfect color opposition of Yellow and Blue.
The two colors highest in chroma and  intensity  in the painting.
