Is Deluminate safe?

Inverts webpage brightness to create a darker browsing experience while preserving colors.

This extension darkens bright websites by inverting the luminance of rendered pages, aiming to keep colors and images from being distorted. It includes modes such as smart invert, supports URL-path-based inversion settings, and can autodetect dark mode.
