As I am gradually going gray, I’ve noticed individual hairs that are gray at the tips and dark by the roots- isn’t that backwards?

Same. I looked it up once and the answer was that the cells that produce the colour are dying. They’re sort of sputtering out melanin at that point but not consistently.
Hairdresser here!
As far as I know your natural hair color is determined by the melanin (pheomelanin or eumelanin) in your body. (As is all color in your body ie. skin & eye color)
Gray hair is just hair that is void of melanin.
As the levels of melanin in your body change it influences the color, or lack there of, in your hair.
The hair shaft is like a timeline. Just so happens at the time of those grays coming in you didn’t have as much melanin!
Your Vitamin C intake increased recently? I wonder if it’s possible for cells to stop producing colour and then start again
