2D histogram of the u − r colour and stellar mass of isolated KiDS-bright galaxies. We divide our galaxies into canonically early- and late-type galaxies, based on either Sérsic index n or u − r magnitude. When dividing by Sérsic index, we define bulge-dominated (early-type) galaxies as those with n > 2 and disc-dominated (late-type) galaxies as those with n < 2 (red and blue points). When dividing colour we define red (early-type) galaxies as those with m_u − m_r > 2.5 and blue (late-type) galaxies as those with m_u − m_r < 2.5 (above and below the dashed horizontal line).
