Camouflage, among other things. In my view, camouflage is the best-guess for the 'original benefit'. The thing about camo is, it's benefits can accrue at any moment in the lifespan, and irregardless of climate, age, sex, or dietary preference. Nor is there any associated behavioral requirement.

Camo would also restrict colors; no bright red, green, etc
