Color-color diagrams based on the WISE magnitudes comparing Seyfert galaxies of type 1 (black) and type 2 (yellow) with generic mid-IR sources selected in a random region of the sky (see Massaro et al. 2011, 2013a,b, 2016, for a similar analysis). Seyfert galaxies of type 2 appear to be redder than those of type 1, and are quite separated in the W1–W2 vs. W2–W3 color-color plot in the left lower.
