You betcha, kemo sabe. The decks were usually Blaugrau 58.1 (that's Colourcoats KM 12), or sometimes Schlickgrau 58 (Colourcoats KM 11). The underwater hull on the S-100 class was most often Schiffsbodenfarbe III Grau 1 (Colourcoats KM 05); any that had red antifouling would have used Schiffsbodenfarbe III Rot 5 (Colourcoats KM 04). Schnellbootweiss is Colourcoats KM 10.
