On commercial vessels, the colors have to follow the Solars standards. To make sure there are no misunderstandings in the charts. Many, software for no-comersical ships have much more fancy displays in random colors. Including 3d views of your route with sonar overlays. Satellite maps, but the clarity of the standard colors, or colors close to them as used by are much clearer in my view.
