ahh, bless you Stik, for helping to debunk the "red stripe myth"
what so many modelers call Red stripes, and so many others call Brown stripes,,,,,,,,were Red-Brown stripes just slightly darker than the South East Asia camouflage Tan color,,,,,,in other words,,,,,Red-Brown FS 30117
here is the list of colors and their usage, keeping in mind that the codes were for safetie's sake, so , even though you could vary your Olive Drab body color for paint batches, weathering, etc,,,,,,,,NO ONE that kept his stripes ever painted a Red-Brown stripe where a Light Red stripe should go, etc
Olive Drab 34087,,,,,,bomb body, etc,,,,,varied in shade somewhat
Yellow 33538,,,,,,,,,,, High Explosive,,,,the nose stripes on bombs, missile warheads, etc
Red-Brown 30117,,,,,Low Explosive,,,,denotes rocket motors on rockets and missiles
Dk Gull Gray 36231,,Chemical weapons bodies,,,,,a different gray than the "modern bomb color gray"
Red 31136,,,,,,,,,,,,,,,,Irritant agent, such as tear gas, etc
Black 37038,,,,,,,,,,,,,Armor defeating,,,,,,not used much since the sixties
Dark Green 24108,,,,,Toxic Agent,,,,,nerve gas, etc,,,,the bomb body is the Dk Gull Gray, the stripes are Green for Toxic, or Red for Irritants, with different numbers of stripes for each specific chemical in each group
Silver/Aluminum,,,,,,,17178 Countermeasures
Light Green 34449,,,,,Smoke or Marker (some stores would get the Light Red, instead)
Light Red 31158,,,,,,,,Incendiary or Highly Flammable,,,,,,Napalm, some stores that could be considered as Smoke, but, used to start smaller fires than Nape,,,,,,,this is the real color of that Red "drop tank" in the Osprey Skyraider book,,,,,,,those are really MK 79 Napalms
White 37875,,,,,,,,,,,,,Illuminating
Light Blue 35109,,,,,,,Training
Orange 32246,,,,,,,,,,,Training/Tracking,,,,,,this is the "other" Orange named International Orange, it is much "oranger" than the Redish tinted International Orange 12197,,,,but, both were in use during the same years
in addition, there is a newer bomb body color of 36375 for bombs and some guidance pods,,,,and some parts of modern bombs use both Olive Drab (34088) and 34095 for different parts,,,,,,,,,and some 36118 on guidance pods
the notes are my own, added for the fun of it, lol
as far as painting methods go,,,,,,,I have just recently changed my method from two steps into a three step process, because of the color of primers I have now
now, I paint the bomb or missile with either Olive Drab or White Primer in the location of the stripes, paint some stripe color over those areas, mask off the stripes with Line-O-Tape or liquid mask sliced with a hobby knife, and spray the rest of the weapon with the body color in Olive Drab or White Primer, this saves me tape, because I don't try to mask parallel lines with two pieces of tape,,,,,,,I just mask actual lines with one piece
don't worry about this method getting the lines "too perfect", you will still get enough variation in your stripes to look good,,,,,,if you try to vary too much in 1/72 or 1/48, you could end up with 3 inch stripes in real like looking like they were painted 6 inches away from their goal,,,,,,,,with a 5 inch brush
so, there is my biased perspective,,,,,,,,,,,almost 90% of my collection is/will be from the era where bombs or missiles will be external ordnance
