There is science behind the reasoning for this choice that can be easier explained by learning how the human eyes work in dark environments.
The human eye has two types of photoreceptors located in the retina which receive light, the rods and cones. Rods are responsible for low light vision and the cones are responsible for high light vision. The rods are extremely sensitive to light, more than 1,000 more sensitive to light than the cones.
Longer wavelength colors such as red / orange, have the least amount of impact on our night vision. This capability allows our eyes to focus on red / orange lighting and then back to dark, dim light without loss of focus on objects thus preserving our night vision.

Yes indeed. This is why US Navy ships use red lights at night. Makes perfect sense. The Navy also does this to minimize ship's visibility to the enemy at night. Here's a Navy sailor's video of darken ship at night.
