> The world's bluest pigment =A0 =A0 Bluier then blue

It's not possible to be bluer than blue. But bluier maybe.
Starting at white (or any other colour "point" except blue) you can
'move' (spectrally speaking) towards blue. After arriving AT blue you
can continue moving in the same direction, which is not bluer, but
mayhaps is bluier.

If this confuses you Gargoyle for CIE1931, and you can be sure to end
up even more confused.
