  We explicitly show that the Bern-Carrasco-Johansson color-kinematic duality
holds at tree level through at least eight points in
Aharony-Bergman-Jafferis-Maldacena theory with gauge group SU(N) x SU(N). At
six points we give the explicit form of numerators in terms of amplitudes,
displaying the generalized gauge freedom that leads to amplitude relations.
However, at eight points no amplitude relations follow from the duality, so the
diagram numerators are fixed unique functions of partial amplitudes. We provide
the explicit amplitude-numerator decomposition and the numerator relations for
eight-point amplitudes.
