So I made a few alliances, and I heard that there is a way to color allied Clans different on the map, is that true? And is there any way to defend allied Clans, and help them with resources and such?
You were lied to. There is no way to color a friendly clan a different color. There is only blue (your clan members) and red (everyone else). The only people you can defend, send rss to, or rally with are your clan members.
