Threw this chart together sometime ago when looking around for lighting options. Interior bulb types should be helpful.
Red overheads minimize pupil dilation so that looking away from red illumination to dark surroundings doesn't cause temporary blindness while pupils readjust from light to dark. At the same time it provides enough illumination to read and perform other tasks. Military figured that out long ago. So yes, depending on temperature of color, you can read under red overhead lighting. Phone camera auto focus and resolution has trouble reproducing what can actually be seen, but you get the idea from this image:I want to keep the door lights white but change the front reading and rear dome lights red. I do read in my truck and was wandering if I install the red lights will I still be able to see and read OK.
