Unfortunately, it doesn't work on wikipedia-at least not for me.

Can you "darkify" some images? Sometimes all is dark and there are super light images it's horrible ☹️

Edit: they have the background of the old colors ☹️

Edit 2: some website divs with a the same background color as body but when dark reader is applied, their background color is different ☹️

Definitely helps me with this affliction to light brought on by migraines. Thank you 😊

My eyes are saved.
I would like to have a "dark-ish" mode so as to not have white on black (which also strains my eyes), but I manage with just making everything sorta greyscale and increasing the sepia value.
Would recommend.
