Original WWII footage of USAF P47 fighter-bomber in action:
It clearly shows that tracer ammunition used with their guns was either of a very pale shade of purple, almost white (RGB vaues deduced from a screen capture at 0:21 sec: 189 189 208 to 193 169 195), or pale pink (228 199 179 at 0:25 sec).
The color recorded on film might have been greatly affected by many factors, though as ambient luminosity, background color, type film and film degradation, etc.
Is there anyone who can share any related video/picture?
