This looks great!

suggestion (non-blocking): Create an #EEE color FreeTube icon and title used for this theme in an editor like GIMP, like is done with Dracula. The contrast (pictured below) is a bit jarring. However, given that we don't have this for the similar cases of the Dark or Black themes, I don't see this as an absolute necessity.

Ironically I didn’t make a new one because I saw that Black didn’t have one, I can make a new icon and commit it soon
