Property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics
A property of quarks, with three values called red, green, and blue, which they can exchange by passing gluons.
In the Standard Model of particle physics, a property possessed by quarks, anti-quarks, and gluons that determine rules for how these particles may interact. There are three pairs of colors and anti-colors: red, green, blue, and their corresponding anti-colors (e.g. anti-red).
