I have a friend who is color blind across all colors but yellow. He has a hard time tracking deer and has to call his wife out most times. I've seen a product that you spray and it makes the blood glow with a black light flashlight. Also seen flashlights that are suppose to shine blood by themselves. Does anyone have a review on these products or tips for my color blind friend?
