Videos should only be watched in the dark. May the dark be kinder on thine eyes. (YouTube dark theme)

These are dark themes for YouTube inspired by FT DeepDark.

Also, credit where credit is due for the color palettes down bellow. (@KDE, @horst3180, @linuxmint, Firefox, YouTube and Discord)

Code also taken from youtube-custom-colors-video-progress-bar for the video theming.

classic, material.

Theme as a userstyle here.

Material version here.

Please understand that I DO NOT WRITE THE JS CODE for the userscript. That is automatically generated by userstyles.org. Tampermonkey DOES NOT APPLY MY THEME AS OF C_2.2.0 and M_2.5.1. Because of that please use Greasemonkey or Violentmonkey.

Many thanks to @MechaLynx for his contributions.

Here is a composite image of different colors you can use in the stylish version.

IF you want this as a scipt make sure you go to the userstyles page, choose your color (the color will be changed in the code) ant then install as a script.
