I want a media query to detect when a device is running in “night mode”

[Kilian]

With more and more OSes offering “night mode”—where the screen dims and blues are reduced—it would be nice to have a media query to detect that. Maybe even with a way to (request to) deactivate it for a site or a specific part of a website where color accuracy is important.

This would be interesting for media browsing or editing, but also for smaller stuff like adapting the site’s contrast like you might with light-level and prefers-contrast: low media queries.

I believe @martinbalfanz will be interested in this media query request, as he's been looking into new media query implementations in Firefox's style engine.

@fantasai Would this be covered by Dynamic Range in Media Queries 5? Or is it something that has not come up yet?

[Kilian]

I don't think so (I researched it for this article), dynamic-range is about detecting "hdr" screens, which doesn't say anything about which colors/what brightness is displaying.
