We have studied four-jet angular distributions using data collected with the VENUS detector at the KEK {ital e}{sup +}{ital e{minus}} collider at TRISTAN at c.m. energies between 54 and 64 GeV. The obseved angular distributions are consistent with QCD, but are inconsistent with the Abelian gluon model at the 5% significance level. We have further obtained 95%-confidence experimental bounds on the fundamental parameters of the SU({ital N}{sub {ital c}}) local color symmetry.
