Color Oppositions

Yellow Green is an opaque color,
Sap Green permanent is basically the same color transparent
but lower on the chroma scale because it has some black or dark red oxide added.

Mix it with it's opposite color transparent Dioxazine Purple for a neutral dark.

It takes two transparent oppositions to mix neutral or one transparent and one translucent color,
or 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.
YYYY = As Yellow as you can get,
YYYC = Yellow Green
YYMM = Yellow and Magenta, as Red as you can get.
MMMM = pure Magenta
MMMC = Purple
CCCC = Thalo Cyan Blue
