Midnight Mode by Navneet S

Ever notice how "black" bars on YouTube videos look kind of... gray? Especially annoying on OLED screens, where black is supposed to mean the pixel turns off completely, not a dim glow.

Turns out a lot of video isn't encoded as true black to begin with. Midnight Mode fixes that: it finds those almost-black pixels and pushes them the rest of the way to true black, so your OLED screen can actually do what it's good at.

• One click to turn on/off
• A slider if you want to fine-tune it
• Works on YouTube, Twitch, basically anywhere video plays in the browser
• Doesn't touch your data. Everything happens locally, nothing gets sent anywhere

(Won't work on Netflix/Disney+/Prime Video. Those block this kind of thing on purpose for copy protection.)
