Color tiles on the subscription fee by author name
This script works only on page https://www.youtube.com/feed/subscriptions but loads on entire YouTube, since YT uses AJAX, so if you are on another page and click to go to subs page, it will not load the script if it was set to only load on subs page. This script should change nothing on pages other than subs page (let me know if it does something anywhere else - that's a bug).
It colors every video tile in the subscription feed with a color, based on the channel's name, so two videos from same channel will always get the same color. That way at a glance you can find different videos from the same channel, see if some channel released few videos today, etc.
The list of colors used is predefined in the script, I tried to pick distinct colors, let me know if there are any too similar pairs of colors, or if you have more colors to add (named HTML colors or hex values).
NOTE: in the screenshot I removed all video titles, channel names and thumbnails, to not reveal my own subscriptions, but the real script of course doesn't do that.
NOTE: due to how small the list of colors is, some different channels might end up with the same color assigned to them if you scroll very far down.
NOTE: it also sets the color of text to black, to stand out from the new background color of the tile.
NOTE: not tested in dark mode (but I think it should look okay, let me know if there is trouble).
