The rest-frame U-V and V-J color–color diagram of post-starburst galaxies in this study. Small dots are galaxies in the LEGA-C survey with 0.6 ≤ z ≤ 1.0, color-coded by their EW(Hδ). The dotted lines separate quiescent galaxies at the upper left from star-forming galaxies at the bottom right. Post-starburst galaxies, i.e., quiescent galaxies with strong Balmer absorption, tend to (but not exclusively) be with the bluest V-J colors. Spectroscopy can pick up post-starburst galaxies that would not be identified with photometries.
