Caption: "This composite image of the primordial contact binary trans-Neptunian object (TNO)) (also a Kuiper Belt object (KBO)) Arrokoth (AKA Ultima Thule, AKA 2014 MU69) was compiled from data obtained by NASA's New Horizons spacecraft (2006jan19--) as it did a flyby of Arrokoth on 2019 Jan01. The image combines enhanced color data (close to what the human eye would see) with detailed high-resolution panchromatic pictures." (Somewhat edited.) Yes, Arrokoth is reddish (see Wikipedia: 486958 Arrokoth: Spectra and surface).
