> I've been trying to make "white regions in dark backgrounds" less painful for months, but doing that at the system level on macOS is incredibly hard. I see you're doing it with CSS filters, which make sense in the limited scope of an article. But applying something like that on the whole macOS UI would cause confusion Can I suggest you "my one simple trick" when I was doing the same on Windows? Increase contrast, a lot, in the original RGB space, then only keep the R channel, then invert the picture. It's like doing a "black and white" mode, but as "black and red" and avoids losing "faint colors". Also, you remove the color consistency problem (IIRC the perception of colors is not symmetrical on light and dark backgrounds, I think it was pioneered by Ethan Schoonover for Solarized) BTW the inversion should be optional, to be nice to apps using a dark theme (ex: many terminals by default) and may work best on a window-by-window basis if that's possible on the Mac. The best results are when using a system light theme + light themed apps.
