In World R4:
Red doors (and any door with Red on it, such as a Bicolored Door with a Red spending color or a Combo Door with at least one Red lock) are immune to the Maroon aura and vice versa, Green doors are immune to the Forest aura and vice versa, and Blue doors are immune to the Navy aura and vice versa.
I think this is not reliable because there are frozen red blank doors (and other blank doors of those aura colors) in the original Lockpick. I think the Maroon Doors should be immune to Maroon effect and so on the other dark colors instead.
