with the Real Color Wheel
Color Oppositions
Yellow darkens with Brown as in Yellow Ocher and Mars Yellow.
Brown is dark Yellow.
Ultramarine Blue deepens to a neutral shadow color by adding it's opposite color Yellow,
either a Transparent Indian Yellow Brown/Side or Yellow already deepened to the Burnt Umber hue.
I could have had a full color image if I wanted to make a green by mixing yellow and blue, but I wanted to show just yellow and blue. I should have done a second painting..
Yellow is the undertone of brown as with the water color pigment of old, Burnt Beechwood Bark,
the organic plants "Turmeric" root and "curcuma" root, from India.
Yellow to brown is also stated with the
crystals WAVELLITE and VESUVIANITE and many others.
It takes two transparent oppositions to mix neutral or one transparent and one translucent color,
two translucent colors, or one transparent and one opaque. 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.
