The way that Component Color Cycling works is it cycles between 9 different colors. That means that if you have 10 or more components, you will get duplicate colors. And there is no attempt made to spatially sort these color assignments. It is done, more or less, by the order in which they were created. So, you will also get cases where you have adjacent components with the same color.
Why do we limit the colors to 9? No real good reason, although expanding that number is a bit bigger project than it at first seems, because there are the corresponding color swatches in the browser and timeline that match those colors, so the range of colors are somewhat limited. But, we could probably fairly easily expand this to, say 20 without too much work. But, that would only really push the problem out. If you had a plate with 25 components on it, you would still encounter the case where one of those components' color was the same as the plate.
Why don't we try to do this spatially? That's a good suggestion, and maybe it should be on the Fusion Idea Station. I would encourage you to add it there, and see if others share this requirement. It would certainly be possible to do this, although it is probably a pretty challenging technical problem to solve. But, we could certainly do a better job on this than we do today.
@Beyondforce asked about the ability to set a color in this mode. Today, no, there is no way to override the colors that component color cycling chooses. Perhaps that would be another Idea Station suggestion. But, today, at least, as you have all observed, the colors are not persisted, so we would have to persist them in order for this to be "sticky".
Component Color Cycling is just a little tool that you allows you to get a more clearer picture about where component boundaries are, but it is not a perfect tool. It is limited in what it can do. Maybe in the future we can enhance this. But, for now, you are unfortunately stuck with what is there. I, myself, sometimes just assign Appearances to my components manually, because I know that this is persisted, and the colors will be the same the next time.
Sorry not to have better answers here.
