About this extension
Fiat Luxia is a browser extension for those who believe the web should be seen, not squinted at. While the world descends into the shadow of dark-themed fads, our deity stands guard to restore the natural order of photons the human eye was built to appreciate.
Using the divine math of Relative Luminance (Y=0.2126R+0.7152G+0.0722B), this extension detects when a website has surrendered itself to the forces of darkness and performs a smart inversion, restoring a healthy, light-themed sanctuary for your eyes.
“May it be a light to you in dark places, when all other lights go out”. - Galadriel
