I actually prefer text as #fff and background as #000. Lower contrast just seems harder to read. I suppose it depends on brightness setting. Also from an article in Nature. “Impact of text contrast polarity on the retinal activity in myopes and emmetropes using modified pattern ERG” 09 July 2023. “Recently, reading standard black-on-white text was found to activate the retinal OFF pathway and induce choroidal thinning, which is associated with myopia onset. Contrarily, reading white-on-black text led to thicker choroids, being protective against myopia. Respective effects on retinal processing are yet unknown.”
