The excess in top quark forward-backward asymmetry has been a hot topic in recent years. Although there are many proposals to explain it, most of them can not fit the differential distributions well. The color octet axial-vector like particle, with mass near the top quark pair threshold, is still a good description of the differential distributions. We study how to distinguish the color singlet and octet mediating particles in top quark pair production by adopting the color flow method. For the first time, we show that such a proposal for the froward-backward asymmetry can be cross-checked indirectly at the LHC.
