Do I need to apply for multiple patents for different colors in the appearance patent?

Color protection is the most important protection content of appearance patent protection. If the same series has different colors, it is best to apply for them all. For example, if you don't apply for registration of combinations of different colors, the other party may not be convicted of infringement because one line in the grid is different, so the more comprehensive the better. However, if the enterprise thinks that the cost is too high, you can suggest him to make several representative or commonly used patents, because you have several patents, which may be only a combination of two or three of them, or may constitute infringement.
