Gamma Ray Bursts (GRB) prompt energetics, though widely dispersed, correlate with their spectral peak energies. The dispersion of this color-energy correlation is reduced if GRB energetics are corrected for the jet opening angle leading to the possibility to use GRBs to constrain the cosmological parameters. One of the issues presently debated is the possibility that these correlations are due to instrumental selection effects. Through the time resolved spectral analysis of Fermi bursts, it is shown that a color-luminosity correlation exists within individual GRBs and that it is similar to that observed among different bursts. This result reassures against the possibility that the color-luminosity correlation is due to selection effects and calls for a robust physical interpretation.
