  We present the contributions to electric dipole moments (EDMs) induced by the
Yukawa couplings of an additional electroweak doublet of colour-octet scalars.
The full set of one-loop diagrams and the enhanced higher-order effects from
Barr-Zee diagrams are computed for the quark (chromo-)EDM, along with the
two-loop contributions to the Weinberg operator. Using the stringent
experimental upper limits on the neutron EDM, constraints on the parameter
space of this model are derived.
