Here is what camo is geared towards ,
humans.......................... marketing tactics makes you think that if you have a hard time seeing it the animals will too.It is the biggest sales scam in outdoor gear bar none especially with the markup on clothing.
When is the last time an animal told you that they couldn't see you but your hunting partner did?
Order of importance IMO.
1-Scent control.
2-Movement.( 2and 3 pretty close and could be interchanged IMO)
3-Noise
4-Silhouette/Lighting/Shadows
distant 5th..............
5-Color/camo
Beat their nose and their ears and you will usually do alright.
Yes some animals have different/better primary senses than others but camo IMO is a fair bit of snake oil.
