But by the time you get to the level of the proton itself, there's no
net color. It's all internal.

No, gluons are exchanged between quarks. And it's this combination of
quarks and gluons that make up the nucleons. The force holding the
nucleons together, strong as it is, is merely a residual force much
like Van der Waals.

residual of which force (the force of the gluons?)?

That's correct. The gluons act as the force mediators between
individual quarks, binding them together into the individual nucleons.
It's only the residual effects of these internal forces that seem to
bind nucleons together.

ok but unlike der Waals, is this residual also a gluon exchange (just
less gluons are exchanged?) ?

Forget about gluon exchanges. That's just a convenient and statistical
way of dealing with QCD gauge fields.

Ok but what i was asking is how come the gluon residual of the protons
(hydrogen) doesn't form a nucleus (and I presume neutrons alone cannot
combine into a nucleus)?
Therefore it's the gluon residual only between the neutron and proton
that forms a nucleus?

It's the Van der Waals equivalent of the strong interaction that hold
nucleons together.
