We have the same problem with the Jurassic Park Jeeps. In the film the bands look orange, but when you see dayligt photos of the original today, the color is red.
Filters used on cameras often distort the colors.
The next problem, even when you have the actual artifact, is dertermining how much it may have faded after exposure to UV light for 25 years.
Another problem is that maybe the supplier needed to provide both red and orange ones to meet the film requirements. The real answer might lie in going to the original manufacturer and see what color was even sold back then. If the factory says they were orange, they were orange, if said it was red, it was red. It is also speculation as to when a red becomes oragne and and orange becoms red.
