Up Quarks
All the 6 quarks come in 3
colors, or flavours, red, green and blue.
The antiparticles have been
assigned the “anti” color, based on an additive color system, cyan, magenta and
yellow. In addition to the color change, the transparency/opacity of the
colored surfaces of the particle has been reversed. The inverted transparency
is to accommodate the colorless particles such as the most of the bosons and
the leptons.
Down Quarks
Since Up and Down Quarks
both are 1st generation particles, but with different mass, they
have been given the same number of geometric elements, just inverted in
positive and negative space.
