Check out my most recent creation using this generator. Color can also be changed on the map as well but I personally like the default Atlas theme for the map that they have and I usually always use the square setting. With this map generator Dungeon Masters are able to change the shape of the map as well as dictate the amount of water to land and ice to land. The one I use the most from this site is the Fractal World Generator. Donjon is an incredible site that has all sorts of world building tools.
