To investigate the difference between $r_{\\rm e,light}$ and $r_{\\rm e,mass}$, we find that $r_{\\rm e,light}$ is larger than $r_{\\rm e,mass}$ for both quiescent galaxies (QGs) and star-forming galaxies (SFGs). Moreover, the difference between these two radii is clearly correlated with galaxy stellar mass, $r_{\\rm e,light}$, and the rest-frame $U - V$ color.
