(B − V) vs. (V − R) plots −left column − and (V − R) vs. (R − I) plots −right column − including the reddening line. Solar colors are indicated with the ⊙ symbol. Top panels: all objects, Haumea family objects, and retrograde objects. Middle panels: Centaurs. Bottom panels: scattered disk objects (SDOs), and scattered or detached Kuiper belt objects (SDKBOs). The stronger correlation between (B − V) and (V − R) colors than between (V − R) and (R − I) is clear. Apart from the solar-like colors of Haumea family objects and the two color groups of Centaurs in the (B − V) vs. (V − R) there is no apparent relevant difference between the color distribution of each family of objects.
