Color charge is the <gauge group> charge of <Quantum chromodynamics>, associated with its $SU(3)$ symmetry. A <quark> transforms in the fundamental three-dimensional representation, an <antiquark> in its conjugate, and a <lepton> is a singlet. The word color is a label for this charge, unrelated to visible light.

The muon is the negatively charged second-generation <lepton>, with <electric charge> $-1$ and <lepton number> $+1$. Its <antiparticle> is the <antimuon>.

The muon neutrino is the neutral <lepton> coupled to a <muon> by the <weak charged current>. It carries <lepton number> $+1$; its antineutrino has the opposite <lepton number>.

A lepton is a <Standard Model fermion> without <color charge>. The charged leptons have <electric charge> $-1$ and their corresponding <neutrinos> have charge zero. There are three generations; their <antiparticles> carry opposite <electric charge> and <lepton number>. Charged leptons and neutrinos have <lepton number> $+1$, with the corresponding antiparticles carrying $-1$.
