> There’s a reason we don’t write white text on black paper.
Because wood is bright and you can’t really print white ink on a black paper?
There might be a usability advantage but using black ink on white paper doesn’t really prove that, that’s just the easier option of the two possible choices.
It’s easier, sure. Especially at first. But we’ve had paper for a while now. Different colors of ink too. If light text on dark background was superior, we would be using it. And could have for hundreds of years for anything considered important.
