Looking at the B/W photo, a red door is a reasonable conclusion. It looks dark like the other red paint. Also, you know that right door is red and you can see the small plate with holes on the lower nose is red on both sides. I would not even question there being red on the left door.
as to the black striping, the color photo seems to show black stripes on the doors. The B/W photo shows there is no black on the top of the wings for the inner stripes. Either the strip was bordered with black only on the doors or just on the lower wing. It is also possible that the yellow and red bled together in the color photo. Experiment and pick whichever you like best. Remember that there are no perfectly accurate skins and that skinning is the nexus of reference, reasonable assumption, and artistic license.
