Here's my CMYK wheel using just the three primaries, Cad. Yellow Lemon, Magenta, and Thalo Blue. Notice how "orange" resulting from Yellow and Red is rather subtle. Primaries: Magenta, Yellow, Cyan. Secondaries(result from mixing the Primaries): Indigo=C+M; Red=M+Y; Green=C+Y. Tertiaries(result from mixing a primary and a secondary): Blue=100%C+55%M=Indigo+Cyan. Purple=55%C+100%M=Indigo+Magenta. Rose=100%M+55%Y=Magenta+Red. Orange = 100%Y+55%M=Red+Yellow. Lime=100%Y+55%C=Yellow+Green. Aqua=100%C+55%Y=Cyan+Green.

In comparison, I decided to take the ready-made tubed colors and compare them to the above wheel. I left the primaries as they were. As Orange, I used Cad. Orange, and when it reproduced on computer, notice how it has almost pink quality. Beside, is the mixed version  which replicates the Mix-It-Yourself(MIY) color precisely. Red: Cadmium Red. Although a little brighter, the color comes very close. On computer though, it looks darker in value now and the MIY red looks more true to what red should look through a prism. Rose:Scarlet Crimson and beside the mixed version; Purple: Dioxazine Purple and side-by side the mixed version. Wow! Exact match. All colors are also mixed with Lead/cremnitz White at one end, and Ivory Black on the other. Purple, mixed with black, makes a very deep black. Indigo: Ultramarine Blue. Tertiary Blue: Cobalt Blue. Aqua:Turquose Blue. Compare it to the above wheel and it's a precise match! Green: thalo yellow green is too dark for the wheel, more yellow needed. Lime: Yellow Green.

just "explode" the colour - don't let the study of it constrain your useage. In other words Don't over-think it.
