I've found this bookmarklet to work pretty well on most website: https://lnikki.la/articles/night-mode-css-filter/ https://lnikki.la/articles/night-mode-css-filter/ I added it as a toggle-able script for TamperMonkey so I don't have to click on the bookmarklet on every page, and changed the 'invert(1)' bit to invert(.9) so it's not full black.
