I'm looking at parts for a DIY headlight, and am trying to figure out what color LED will give me the best range (distance) for trail riding at night. While 5000/6500K seems logical, I've seen an instructible where a guy used turquoise (green/blue), and made the argument that he could see farther. That makes sense as the rods in my eyes respond best to that color, but how does that translate to illuminating dirt, leaves, and logs on a rainy night with no lights for miles? Would warm white be better here since most objects are brown and green in the woods? The guy also mentioned that green was next best on night vision. (Remember, we're not talking about preserving unassisted night vision, or contrast lighting, which red light is good for)
