How to change the box color of every class?

In my task, there are blue_obj, green_obj, and yellow_obj, but they are displayed in boxes of different colors, which makes it very difficult for me to review the annotations. After I directly modify the color of the box, the next image will not take effect. How should I modify the color of the box to specific color?

For example, blue_obj may be displayed with a yellow box, while yellow_obj may be displayed with a blue box, which is very confusing 😭 .
