Mean position of each Hubble type in the color-magnitude diagram, using the absolute u − r color for all EFIGI galaxies with Incl-Elong ≤ 2. One sees a similar “S” sequence as in NUV−r color (see Fig. 5), but without the additional spacing of S0⁺-S0a and Sa-Sab types that generates the Green Plain. The central point with very large error bars correspond to the rare cE types, whereas dE are located at ( − 17.8, 2.6), away from the “S” sequence.
