Rest-frame (NUV−r) vs. (r−K) colours for VIPERS galaxies at z = [0.62–1.2]. Isophotal contours outline the loci of the whole VIPERS flux limited sample (contours are in steps of 10% with the faintest isophote level starting at the 10% level). The grey open circles represent all [NeV]λ3426 emitters in the flux-limited catalogue. The dashed green lines show the region of the green valley as defined in Eq. (1). This is surrounded by a 0.25 mag wide region which we have excluded to account for colour uncertainties. The comparison samples of the red and blue galaxies occupy the regions above and below the solid grey line, respectively. The filled circles – colour coded according to their classes, show the [NeV]λ3426 emitters extracted from the stellar mass−redshift matched sub-samples.
