Red is often recommended for preserving night vision, because the rod cells in our retinas are fairly insensitive to red light. However, I personally find that dim green light is much more pleasant, whereas red light is either harsh and mildly painful, or too dim for me to see clearly. (judging by the colors of about half the car dashboards on earth, I'm not the only one.) I'm curious to see which colors other CPFers prefer.
Please don't re-hash the old arguments about the sensitivity of rod cells, or insist that shorter wavelengths must ruin night vision regardless of what a person thinks they're seeing. Everyone's eyes are different, and there are lots of factors (such as relative concentrations of different-color cone cells, and the exact focal properties of each person's eyes) that can cause shorter wavelengths to be a better compromise for some people, while other people can see just fine with longer wavelengths. That debate is just an extension of the Cool Tint vs. Warm Tint debate, and it has been beaten to death so thoroughly that it can't even be identified by dental records.
I'm just interested in collecting people's personal preferences based on experience. Also, if anyone has a favorite single-color flashlight that they use for preserving their night vision, feel free to share suggestions in case others are having trouble finding what they need.
