Answer: First of all, color combination trademarks do not limit the specific shape, and designated color trademarks must have a fixed shape: for example: the color combination trademark composed of white and blue for 'Colgate' toothpaste, toothpaste squeeze The shape of the color combination trademark depends on what shape it comes out, while the shape of the designated color trademark is fixed. Secondly, the distinctiveness of a color combination trademark lies in the color, while the distinctiveness of a designated color combination trademark lies in the combination of graphics and colors; thirdly, a color combination trademark with only one color lacks distinctiveness, while a designated color trademark with only one color does not. For distinctiveness, a designated color trademark can be composed of many colors, while a color combination trademark may be too complex to register if it is composed of too many colors. Note: There is one requirement when applying for trademark registration: whether to specify a color and what color to specify. If a trademark specifies a color, it means that in future uses of the trademark, only the specified color can be used, and no other colors can be used. If no color is specified, there are no restrictions on subsequent use of the color. Therefore, it is recommended that trademark applicants generally not specify colors.
