> The problem is the contrast ratios. The contrast between 0% black and 100% white on a good screen is so high, it physically causes pain, even migraines.

Maybe that means you need to turn down your screen's brightness.

No, that’d be exactly the wrong solution.

Because then displaying color-calibrated content on your display (such as movies, games, photos) is also completely distorted.

Instead, we need a way to specify CSS colors relative to a colorspace and contrast ratio.

It's called sRGB and it supposedly has a "black point" which is not entirely black. Nobody uses it though, on photos it would be useless. Also for me black on white is perfectly fine in a well lit room. White on pitch black is indeed problematic. Anyway, it could be a user/browser preference instead of a designer preference.

Lowering brightness shouldn't distort color-calibration too. You are supposed to match your brightness to the surrounding lighting too.

Correct, but it requires recalibration if you lower the brightness (as no screen has a perfectly flat curve)
