2. The scope of applying for design patent with or without color protection is very different! If you apply for color protection, the protection scope is small, and this patent can only protect this color. If someone changes the color, it is not covered by your patent. He can't infringe your patent, and you can't sue him for infringement. If you don't apply for color protection, then your patent will protect all the colors of your product appearance, and the scope of protection will become wider. No matter what color others use, as long as the appearance is consistent with your patent, you can sue him for infringement and demand compensation.
