There are already existing many JOSM paint styles for different usecases. But didn't you always felt like hm yes this is very useful but I would prefer if it shows in red instead of green because in my area this is not visible enough. Or you working with a special niche data that haven't been covered by another paint style yet. Why not make your own? Let's explore the openness of JOSM and use it for our benefit.
