In this moment there is only 1 color of paved ground. My idea is maybe not important for gameplay, and even a bit silly, but I like buildg my camp and features related to this. I'm sugesting using items like charcoal to recive diffrent color of paved ground.
Using items like rustroot will give red(rusty) color, blueberies - blue, and charcoal - black. The resources may be diffrent, mechanics as well - like paving with charcoal.
Please discus, and be gently with me [;
