Color–color diagrams BzK (left), uRJ (middle) and uVi (right) used to select our star-forming galaxies. In each panel, the galaxies whose spectroscopic redshifts satisfy the redshift domain of each color criteria utilized (indicated in each panel) are represented by black squares, while the remaining galaxies are represented by crosses. The circles are the galaxies whose spectra showed broad emission line features. These galaxies revealed spectroscopic redshift z> 2.0. The solid lines delimit the selection zone used by each criteria with the smallest region indicating the expected location of the passive galaxies.
