Color-color diagrams based on the 2MASS magnitudes comparing contours of Seyfert galaxies of type 1 (gray-to-black) and type 2 (yellow-to-green) with generic sources selected in a random region of the sky (see Massaro et al. 2011, for a similar analysis). While Seyfert galaxies occupy a distinct region from that of generic infrared sources their near-IR properties are quite similar. Isodensity contours are computed using KDE (see, e.g., D’Abrusco et al. 2019).
