Lattice Quantum Chromodynamics (Lattice QCD) is the theory of quarks and gluons formulated on a space-time lattice. The formulation of quantum chromodynamics on a discrete rather than continuous space-time resolves many difficulties (e.g. divergences) associated with the continuum field theories. Most importantly, Lattice QCD provides the framework for investigating of non-perturbative phenomena such as confinement and quark-gluon plasma formation, which are intractable by means of analytic field theories.

That QCD predicts this behavior was first discovered in the early 1970s by David Politzer and by Frank Wilczek and David Gross.
The three kinds of charge in QCD (as opposed to one in QED) are usually referred to as "color charge" by loose analogy to the three kinds of color (red, green and blue) perceived by humans.
QCD is a gauge theory of the SU(3) gauge group obtained by taking the color charge to define a local symmetry.
