Hi! A pair of months ago, I created a post with an issue in AGD 4.8. The colours of the sprites were yellow instead of white. It turns out that this morning (don't know why, but I was suspecting something) I loaded UFO game and there it is!! The ink colour in block number zero was yellow!!!! So all sprites too!! Anyway, today I have already learned to solve something that was driving me crazy. And, in a way, it can also be a good trick to define the default sprite colour in a project.
