Disk g − r absolute color evolution in the galaxy color-mass diagram. Left: color-mass diagram for all EFIGI ∩ GALEX galaxies with Incl-Elong ≤ 2, in which the color of the points represent the disk g − r absolute color inferred from bulge and disk model-fitting. There is a systematic reddening of the disk along the Hubble sequence from irregulars to ellipticals. Right: mean value of the disk color (g − r)_disk for EFIGI ∩ GALEX galaxies in color-mass cells of 0.5 dex in total stellar mass and 1.5 in NUV−r color. Only the bright part of the Blue Cloud, the Green Plain and the Red Sequence are shown. The associated error on the mean and the number of galaxies in each cell are indicated. There is a significant reddening of the disk for redder NUV−r colors, as well as for earlier and earlier types along the color-mass sequence.
