We study CP violation in a chiral color model with exotic fermions transforming as singlets of the weak-isospin group SU(2${)}_{\mathrm{L}}$. The Higgs sector consists of a nonet of chiral color and the usual doublet of SU(2${)}_{\mathrm{L}}$×U(1${)}_{\mathrm{Y}}$. In the limit in which the mixings between the third generation with the first two generations are small, CP-violating interactions are dominated by the exchange of neutral Higgs bosons. The CP-violating parameters ε and ε’/ε for the kaon system are easily accommodated. The neutron electric dipole moment is generated at the one-loop level and is ∼${10}^{\mathrm{-}25}$–${10}^{\mathrm{-}26}$e cm.
