Addon simply works immediately. You can adjust colors, e.g. on YouTube, video. Usually colors have reduced saturation, and even contrast, e.g. from cameras, old movies. You can brighten dark places. And in bright lighting, sometimes there is no black and dark colors at all. And it does not work globally. I recommend.

Extremely helpful to make the video more pleasant with color corrections! The channel-specific setting option is simply a dream. Would recommend it to anyone who values a beautiful video saturations!!
