Dark/Night Mode

it's a chrome extension. you literally click once to install then select the colors you want...

And there's a big difference between me just arbitrarily choosing dark tones and an actual web designer making a properly made version. I can make a really really ugly dark mode with a chrome extension, yes, but that doesn't solve anything for non chrome users and also isn't a great experience cause it'll be ugly.

As a colorblind person, the thought of tinkering with this is the stuff of nightmares. I’m glad it’s an option for some but it’s not a universal fix for everyone. 

Just install Night Eye - it has a few months free and is pennies after that. Also the free version allows 1 site in dark mode forever.
