  We consider the phenomenology of CP violation in a color-octet extended
scalar sector for t\bar{t} production and decay at the LHC. In particular we
study the effect of the two neutral color-octet scalars S_I and S_R that occur
in the model. There are two new sources of CP violation: a phase in the
couplings of S_{I,R} to top-quarks; and two phases in the quartic couplings of
the scalar potential. In resonant production of a single S_{I,R} followed by
its decay into t\bar{t} pairs through the parton level process gg to S_{I,R} to
t\bar{t}, we find large raw CP asymmetries which can reach 12%. These raw
asymmetries are, of course, diluted by standard model (SM) t\bar{t} pairs
making observation of CP violation contingent on whether the resonance itself
can be extracted from the SM background.
