Mean metallicities and ages of the full galaxy sample at z = 0. Less populated classes are in front of larger ones for visibility while slightly decreasing the perceived scatter of the larger classes, such as the early-quenched galaxy class. This class concentrates at high ages and lower metallicities opposing main-sequence types. The intermediate classes of late-quenchers and rejuvenating galaxies bridge the gap in a dichotomous way of age and metallicity combination.
