That's a mystery, isn't it. The patent abstract for KORprolit mentions nothing but red, like the picture. It could be a name mixup by a producer, or it could be reuse of the trademarked name by Kordes. Kordes has neither name on its present website, other than to list CHICA KORDANA with the code name Korprolit and to show the patent number. It also lists a different Kordes rose named CHICA with the code name Kortachomet, about which there is scant information.
