That he may be, but Green is one of the three primary colors. At least
in additive color mode Red Blue Green. If you are talking about
subtractive color, it is Cyan Magenta Yellow. Add black and it becomes
the standard printing system.

True, but the "primariness" of the colors in these various color
systems are far from universal. These colors are "primary" only with
regard to the visual systems of human beings (and some other primates)
which have a particular type of three-pigment visual receptor system.

Animals which have significantly different visual pigments in their
optic receptors (and there are many!) would tend to have a different
response than humans to various mixtures of red, green, and blue
light... e.g. the "red light plus green light equals a yellow color"
mixing trick would not necessarily work for them, as this is a
perceptual "trick" of the human visual system. Although human eyes
may not be able to distinguish between a red/green mix, and a true
narrow-band yellow, a spectrograph (or a simple prism!) will
demonstrate that they're very different!

If Art is actually claiming that there's some sort of binding or
correspondence between the three families of leptons, and the "three
primary colors" as seen by humans, then the only such correspondence
I'm aware of is that both have the number "three" associated with
them. There's no physical correspondence deeper than that, to the
best of my knowledge.
