Is there a japanese word for "reincarnating into the future and being even more OP because society/technology has regressed"? I
really don't want to defend this generic crap, but i still fell compelled to point out that this isn't an isekai.
Isekai is when someone is transported to another world. That's all. Nothing else. It's just that a lot of the recent isekai popularized many tropes. They were then copied by even less skilled authors, who were themselves copied by more bandwagon hoppers.
Overlord = isekai
Youjo Senki = isekai
Shield Hero = isekai
Digimon = isekai
Sword Art Online = isekai (debatable)
The Wizard of Oz = isekai
Death Mage = isekai
Now, the author could do that thing a few others have done where they reveal the MC was from another world after a few chapters (what a twist!), but so far there are no signs of this being the case.

It looks like the author already revealed his gimmick. White is the easiest to use, but has the lowest ceiling. Magic has apparently degraded enough that few (if any) people ever reach even the low ceiling for white magic leading people to think white is the best.
Gold (MC's) is poetically the hardest to learn, but has the highest cap. The previously mentioned degradation means that everyone thinks it's trash tier since no one can reach the higher cap.
Basically the same shtick as the inferior eye magician (or some other generic future reincarnation story, can't be assed to double check).
