It turns out that
fully consistency with the
|
|
|
hadrons requires
that each quark type comes in
|
|
3
species which will symbolically
be denoted as
|
|
|
red , blue and green .

Observed hadrons
only correspond to
|
|
|
combinations that
are white.
|
|
|
• |
For example : proton is u(red), u(blue) and
|
|
|
d(green).

The analog of photons are gluons and they
|
|
|
come in 8
colours.
