For brighter, bolder colors like Stellar (as well as Hummingbird, Armadillo, Sassy, Countess, Clementine, Mirror, Twilight, Albert, Dazzle and Moonbeam), we recommend washing these diapers with ‘like’ colors for the first few washes to avoid any transfer of dye to other lighter colors. These do not have to be six consecutive washes before your first use. You can also wash these darker colored diapers together. The same goes for light colored diapers — wash ’em together before mixing with others.
