After a trademark is registered, it is generally not allowed to change the color of the trademark at will.

Trademark registration is based on specific trademark graphics and design elements, including combinations of colors. The trademark registration agency will review and register the trademark pattern submitted during the application, which means that the color of the trademark is specifically determined at the time of registration.

If you want to change the color of a registered trademark, you usually need to make a trademark change or resubmit a trademark registration application. This involves re-examination and registration procedures, and needs to meet the requirements and regulations of the trademark registration agency.

It should be noted that the color of a trademark can have a certain degree of flexibility in commercial practice. When using a trademark, appropriate adjustments and changes can be made within a certain range to suit different media, materials, and backgrounds. However, these changes should be made without altering the overall identity and core features of the mark.

If you intend to change the color of your trademark, it is recommended to consult a professional trademark agency or lawyer to understand the specific legal regulations and procedural requirements to ensure compliance with relevant laws and regulations and to protect trademark rights.
