That is the color wheel we will be copying, don't darken each color yet.
Painting a full color wheel with three transparent primary colors is simple. Draw a circle.
At the top-middle of a ten degree pie shaped wedge is the first primary color, a dual-toned orange-to-yellow transparent primary. Cadmium Yellow Light opaque is the same hue as a tint of Indian Yellow O/s transparent. Read Red Right
Primary Transparent Magenta is 120º to the right of yellow. Add white to get pink.
To the left of yellow is Primary Transparent Cyan, add white to get O.H. Scheveningen blue deep opaque. This completes the circle and the primary triangle.
To make a secondary color add 100% of the primary colors as shown in black. Because the pigments are transparent they can be painted in any order.
If your painting a full colorwheel including the darks, use the opposite color to darken each color not black. Darken the mass-tone of transparent yellow with Burnt Umber and the mass-tone of cyan with Ult. Blue.
This is the yellow printing plate of the RCW color wheel. Black represents yellow. #31 to #7 are solid yellow. From #30 to #26 are 80% yellow, 60%, 40%, 20%. Number #25 cyan has no yellow in it, #13 magenta has no yellow in it either.
black is yellow in this plate. Colors from yellow to red use the red's brown to darken their color.
Black is magenta in this plate. Adding the opposite color, cyan, to red will make a dark brown,
the same color which will also darken orange and yellow to dark brown. Dark brown is one step away from neutral dark.
Black is cyan in this plate. Start adding Magenta to cyan at #25.6 (the 6th block down) to make dark cyan. #25.7 should look like ult. blue.
The cyan to blue wedges use blue's dark. The yellow to red wedges use red's dark.
Yellow Magenta Cyan Plates in color, no opposite colors added to make darks.
You can print and color this one in.

My painting of a Real Color Wheel in acrylics.
3 primary pigments coloring water, 3rd grade students
Start with 6 clear glasses filled 1/2 way with water. Get plenty of clean water for painting. Clean water and brush for each color. Use the tip of the brush to pick up a little color and merge it in your display water .
This image is in RGB Color Space and as an RGB it prints with a 20º color shift in blue and cyan.
The color shift doesn't show up in RGB but it does when you print it.
Here is a list of RCW PIGMENTS from Old Holland and Sennelier from one retail company.
You don't need the Caput Mortum, Thalo Green Turquoise Opaque, Cyan blue opaque or any of the tubed whites. Do get the O.H. Phthalo Blue Green/Shade instead of the Blue/Shade.
Jar white has a better stroking consistency.
