Fig. 1 (Color online) A sketch for the decomposition of ${f}_{\alpha}^{\textrm{dif}}$, which is exerted on the particle $\alpha$ by the surrounding colloidal particles. In the figure, the blue arrows represent the velocity of particles, while the red arrows stand for different contributions of the solvent-mediated hydrodynamic force. In addition, the pink arrow represents the reflected velocity field by the particle $\gamma$.
