Hello! TK of the Kaleidoscope Tavern here. I was recently trying to research how to do this, and just came across archived threads asking about it or suggesting it as a feature. However, after some messing around, I figured out that you can, in fact, do this already. Perhaps this exists somewhere in the documentation, I do not know, but I wanted to post this so that anyone in the future asking the same questions I was can find it easily. So this is not a question itself, but rather the answer to a question asked in an archived thread, specifically that of Kronos Wyrm and the suggestion made by Owen O. I wish I could have given y'all this answer less than a decade later, but better late than never, I suppose. If you would like to have semi-transparency, you will need to add two digits to the hex code in the drawing tool. So, this: Would become this: FF is fully opaque, 00 is fully transparent, and 80 is 50% opacity. It does need to have exactly eight digits or it turns black!
