d4000 versus stellar mass relation of VIPERS galaxies in three redshift bins: 0.50–0.65, 0.65–0.80, and 0.80–1.00. Galaxies are colour coded according to their location in the NUVrK diagram of Moutard et al. (2016b): red points indicate passive galaxies, green points mark those in the green valley, and blue points for those classified as star-forming. Dark blue points mark galaxies with [Oii] emission detected at > 3σ. Solid red and blue curves show the central d4000 values of the red sequence and blue cloud populations as a function of stellar mass, while the dashed curves mark the 1σ widths of each sequence. Black dashed curves mark the 90% stellar mass completeness limit as a function of d4000 for galaxies within that redshift interval. Horizontal and vertical dotted lines indicate the d4000 = 1.55 divider and log ℳ = 11.0 mass limit.
