(B − V) vs. (V − R) color indexes of 2008 YB₃ (black square) and 2005 VD (black diamond). We include colors of some objects in the primitive minor bodies for comparison. See text for references. Background black points are TNOs from Fulchignoni et al. (2008). Empty diamond is the average color of Damocloids from Jewitt (2005). Empty circle is the average color of nuclei of Jupiter Family comets from Lamy & Toth (2009). Red and blue squares represent the red and blue groups identified by Melita & Licandro (2012). Asterism represents colors of Trojans from Emery et al. (2011). In this representation we do not distinguish between the two groups identified by Emery et al. (2011) because they are not distinguishable in the visible wavelength. We include 2008 KV₄₂, a retrograde TNO, from Sheppard (2010).
