The trouble with trying to mix blue and red is picking the right blue and
the right red. These colours are not just linear, with red at one end of
the continuum, blue at the other and CPR red somewhere in between. Not only
are there multiple hues that theoretically mix to different purples or
maroons or browns, the pigments in paint don't follow the rules as obviously
as when light is mixed to make colours on your computer. As a guy who
dabbles in artists colours, it is crucial to start a mix knowing how the
various pigments react with each other - you can easily produce a ghastly
greenish shade of brown. Since model paints are usually not pure pigment
colours (they are mixed from various pigments) it will be highly
unpredictable and you'll buy a lot of those little bottles before you find
an acceptable combination - assuming it is even possible with colours on the
market. Personally, I doubt there is a true red and a true blue presently
sold that will mix to a CPR maroon colour. In my view, it is easier to
start close and then try tweaking it.

Hmmm. I wonder, if you started with SP Scarlet (or another "red" red) and added dark blue, drop by drop, if you would eventually end up with an acceptable CPR color?

Adding it. The idea is to lighten it without pink. Using a less "blue" red
to tone down the CP colour achieves that - although the mix is tricky.
Sometimes I wonder whether the result doesn't shift too red - but that is a
factor of the mix, not the method. Its like the school kids paint set -
put red and blue together and you get purple, but if you put in more blue it
shifts blue; put in more red (as suggested here) and it shifts red.
