Apple adds Adaptive Dark Mode to Safari 27.3 beta

Apple's Safari 27.3 beta introduces Adaptive Dark Mode, a feature that automatically converts light websites to a dark appearance when a user has enabled dark mode and the system appearance is set to dark. The feature ignores pages that already declare dark-mode support via color-scheme CSS or meta tags, and otherwise analyzes a page's colors to decide whether to invert them, using a custom color matrix that inverts luminosity while preserving hue and targets WCAG 4.5:1 text contrast.
