A trademark designated color application means that the application must be submitted in accordance with the color sample designed by the customer. Usually, trademark logos designed by designers are in color. If you declare according to the specified color, you will obtain the exclusive right for trademark registration in the future. When using it, you must also use it according to the specified color and cannot change it arbitrarily. Black-and-white application means that the color is not specified. It means that the application is submitted according to the black and white ink draft when applying. In trademark agency practice, trademarks applied for in black and white will obtain exclusive rights in the future and can be used in any color. This is broader than specifying color applications. Generally, professionals recommend applying in black and white.
