Generally speaking, registered trademarks are mostly black and white ink drafts. When using, the trademark registrant can add colors to the registered trademark according to actual needs. However, after adding color, the trademark image should be different from the registered trademark image (black and white ink draft) only in black and white and color, without any substantive difference.

If the colors added to the original registered trademark can form a special pattern or color that can exist independently, the original registered trademark pattern will be divided into two completely different parts, and the overall visual effect of the original registered trademark pattern will be lost. , which is a change of the trademark image.
