36RCW#14, Cool Magenta, Cobalt Violet Phosphate transparent.
36RCW#13.5, Quinacridone Magenta, PR:122
36RCW#12, Warm Magenta, PV19

PR122 quinacridone magenta is the perfect pigment, also the new Opera pigment which looks like a tint of magenta in mass-tone.
Opera has no dark color side like Quinacridone Magenta has.
It makes reds more brilliant than cad and blues more vibrant than Ultramarine.
PV:19 will not make clean blues because it's warmer then PR:122. If you have only one primary magenta it is PR:122.
PR:122 magenta, PY:150 cool & PY:153 Indian Yellow and PB:15.3 (the original) Cyan are all you need to make all colors.
I challenge any other combination of pigments to paint a more accurately correct looking color wheel.
I challenge for this to be taught in schools rather than the red-yellow-blue model that each State School Standards demands.
You and today's children have been taught an old wrong color theory.
Thank you ShinHan Art Materials Inc. for sending me a sample tube of their Special WC Opera water color pigment while Opera was still a newcomer,
without it I never would have tried Opera.

Cobalt Violet Phosphate, Transparent duel-toned is the coolest magenta but not available anymore.
Holbein Opera (PR:122 and BV:10) in direct sun light tests for 8 months show a small warming change
in the tints, not enough to consider it fugitive.
 

Opposite color, Mussini Phthalo Green, Transparent

You can make a dark-neutral with Cobalt Violet Phosphate transparent, a duel-toned pigment,
or 36RCW#13, PR:122 quinacradone magenta transparent, a non-dual-toned pigment mixed
with 36RCW#31 PG:36 Phthalo Green Yellow/side (the original) transparent.
Cobalt Violet Phosphate is a bleeding pigment in oil, use it as a top color or top glaze only.
No other element will make this exact hue.
