This is exemplified by powertool brands which have distinct color schemes for their Tools: Milwaukee (Red & Black), DeWalt (Yellow & Black), Fein (Orange), Makita (Teal), Ryobi (Chartreuse), etc. Some competitors have similar but not identical color schemes, for example Milwaukee vs Craftsman, Fein vs Ridgid. Though I don't think any "own" the colors in the color schemes --but I could be wrong.
