What is Deluminate?
"Deluminate" is a versatile Chrome extension designed to invert the luminance or brightness of websites, transforming bright and glaring white sites to soothing black, thereby reducing eye fatigue and improving user experience. In contrast to other comparable extensions, Deluminate maintains image integrity by avoiding distortion of color contrasts. Note that its effects on page luminance may cause slight slowdown for some users.

Invert the brightness of the web without changing the colors! Useful as a night mode to darken most bright web sites (like Google), or just for making the web soothing black instead of glaring white. Similar to the "High Contrast" or "Hacker Vision" extensions, but tries not to ruin images by blowing out the contrast or changing the colors.

Warning: because of the way this extension inverts the luminance of rendered pages, it may cause noticeable slowdowns for some users. If this happens, you may prefer another extension that uses custom CSS to set the default background and text color of web pages.

I've been using this a couple months now. Works extremely well for me on a variety of sites. Occasionally inverts pictures even when Smart Invert is selected, but that's a minor issue compared to what it accomplishes, even on complex pages. I do not notice much, if any, rendering slow-down. I would appreciate a capability to optionally share site-level preferences across computers (e.g., by storing the configuration in a cloud drive file), but having site-level prefs at all is immensely valuable to me.
