Ask me anything. ANYTHING! o_O
haha thanks yeah it often depends what you're going for in a video... like if you wanted to colour code annotations in the video to mean/refer to certain things then you could have them different colours and its also useful to differentiate them. However, the majority of the time it is just up to the personal preference of the YouTuber themselvesSounds smart.
I haven't used it much, just a couple of videos. One looks a little like a christmas tree, but I "needed" several annotations at one point so had to resort to several colors to make the stand out from each other.
