The revealing anomaly
Already the concept of a tricolour electron can result logically from the anomaly of the classification, in the same family, of the 4 particles currently considered as elementary bricks constitutive of the universe: the quark, the antiquark, the electron, the neutrino.
Indeed, the quark and the antiquark are some coloured particles while the electron and the neutrino, insensitive with the force of color, are regarded as white or colourless, Thus, they should not appear in the family of the coloured particles.
To attach the electron and the neutrino to the coloured family of the quark and the antiquark, they should be integrated in the logical continuation: quark, antiquark, electron, neutrino, presented below, on the triangle of G3. The 3 charges of color are symbolized by 3 small pictograms: a red, a yellow, a blue.
It is normal, because it is an empty set, that the neutrino however does not carry a color, complement of the coloured electron. It really has a relationship with the color.
