We study the color entanglement like effect for T-odd cases in collinear twist-3 factorization. For an example, we compute the transverse single spin asymmetry for direct photon production in pp collisions in a pure collinear twist-3 approach. By analyzing the gauge link structure of the collinear gluon distribution on the unpolarized target side, we demonstrate how the color entanglement--like effect arises in the presence of the additional gluon attachment from a polarized projectile. The result is consistent with that obtained from a hybrid approach calculation.
