Color-mass diagram. Left: color-mass diagram for all EFIGI ∩ GALEX galaxies with Incl-Elong ≤ 2. The color of the points indicates their Hubble type as classified in the EFIGI morphological catalog. The distribution of galaxies exhibits the bimodality between the ellipticals and lenticulars in the upper region (the Red Sequence), and spirals of type Sab and later in the lower region (the Blue Cloud). A lower density region (the Green Plain) connects both structures, with galaxies of types S0a and Sa. Right: mean absolute NUV−r color versus mean stellar mass for each Hubble type for EFIGI ∩ GALEX galaxies with Incl-Elong ≤ 2; the error bars represent the rms deviation within each type. The Hubble sequence draws an “S” shape that could be parameterized monotonously by the mean Hubble type, with the exception of dE at (9.6, 4.9).
