Trademark laws must be consistent, and it is not acceptable to change registered trademarks at will.
However, in actual use, the fonts will not change much, and graphics coloring, etc. are all acceptable. You can compare your registered trademark and the actual trademark together. You can tell at a glance that they are the same trademark. Basically, there is no problem. If it is difficult to tell that it is the same trademark, then it won’t work. If you launch it close to the famous brand, it may still cause infringement.
It is recommended that you beautify the fonts and patterns. Try not to make too many changes. If the changes are too big, you can apply for registration again.
