Relationships between the extinction-corrected rest-frame U − V and stellar mass at 0.2 < z < 0.7 (left) and 0.7 ≤ z < 1.2 (right). The gray contours and mosaics in the background indicate the relative density in the color-mass panel. The criteria from Wang et al. (2017) was adopted to separate galaxies into RS, GV, and BC, respectively, as shown in orange lines in each panel. Based on the morphological classification from Song et al. (2024), the GV galaxies were further divided into two types, including early-type disk (ETD: red) and late-type disk (LTD: blue), separately. Both subsamples excluded the contamination from AGN candidates and considered the mass matching (see Sects. 2.4.2 and 2.4.3 for details).
