Distribution of the g − r absolute color of the EFIGI bulges (or Sérsic component) for each Hubble type (with Inclination ≤ 2). The black dashed line represents the mean color by type and its associated error. Bulge color is overall stable with most bulges in the 0.5–0.9 range. There is a 0.17 mag reddening between lenticulars and intermediate spirals (Sbc), which could be due to dust reddening, as it is more frequently present in large amounts in these galaxies. This effect decreases for Scd types, with some bluing possibly being present for the bulges of Sd and later types, compared to the lenticular and early spirals.
