How do we reconcile ahadith which imply dying one's hair black is haram, given that black hair occurs naturally?

From https://islam.stackexchange.com/q/16162/17163 , we see that there's a bunch of ahadith which prohibit dying one's hair black. For example: >"Some people will dye their hair black like the breasts of pigeons at the end of time, but they will not even smell the fragrance of Paradise."
>Sunan an-Nasa'i 5075 [grade: sahih] However, many people have naturally occurring black hair, which raises the question: **Question**: How do we reconcile ahadith which imply dying one's hair black is haram, given that black hair occurs naturally? Logically, we can infer there are two requirements to this problem: 1. the color black, since dying one's hair other colors was not considered a problem, and 2. the act of dying (not simply possessing black hair), since non-dyed black hair is fine. ---- Other questions on this topic are 1. https://islam.stackexchange.com/q/7222/17163 2. https://islam.stackexchange.com/q/14572/17163 3. https://islam.stackexchange.com/q/38497/17163 4. https://islam.stackexchange.com/q/39091/17163 5. https://islam.stackexchange.com/q/44068/17163 6. https://islam.stackexchange.com/q/44178/17163
