  We present the results obtained on the color distribution of galaxies in the
CFHTLS-Deep Field Survey Data Release 03. Photometric redshifts have been
computed using a standard SED fitting approach, with a new version of the
public code HyperZ (New-HyperZ). Large samples of galaxies with well determined
photometric redshifts in the 0<z<1.3 interval have been selected in the four
CFHTLS Deep fields, within the completeness limit in absolute luminosity in u
and r bands. We study the restframe color distribution of galaxies as a
function of redshift, luminosity and local density. Our results are consistent
with a bimodal color distribution, where red galaxies dominate the highest
luminosities out to z~0.6. An important population of blue and bright galaxies
appears beyond this redshift, increasing with redshift. Out to z~1.3, a strong
evolution is observed, at a given redshift, in the color distribution of
galaxies as a function of luminosity, together with a mild evolution with the
local density at fixed luminosity.
