Other than bringing someone along to help.......one of the biggest things that you can do for yourself is to use what you DO have. Color blind or not you can still see. Take extra care because of your limitations to pay very close attention to the hit, and maybe even more importantly where the animal is going as it runs away. Pay very close attention to it's route, mark landmarks carefully and don't stop watching until it's out of sight completely. The vast majority of well hit (lung/heart/major vessel) animals don't make it very far out of sight depending upon terrain, so many probably won't be laying far from your last noted landmark. If you are afraid of losing that landmark, after you have waited an appropriate amount of time mark where the animal was standing and head directly to the exact last spot you saw the animal. You could easily waste valuable time with blood drying sorting out a trail to the spot you could just walk straight to.
Be very careful hunting in the rain........
If by yourself, look for the "Shine" of blood. A good fresh trail will be wet.If everything in the woods is dry then the blood will stand out especially in an artificial light.

Don't rely on the peroxide, just use it as a tool to compliment your woodsmanship.
