I use net colors in altium. I prefer this in combination with the monochrome mode to do routing as to me it makes it more obvious what should be connected to what.
Is there a way to bulk-random-color nets in altium? Ideally I would like a tool that could do it with some rules (eg, keep groups of nets to certain colors, so for example all power-regulation nets are some tint of red, all nets in a certain filter are some tint of green, etc), but I can live with it being random and me then just changing the few colors I don't like.
