How to change a class diagram background?

In class diagram, the class shape background is blue, How can I change it to white?

I couldn’t find anywhere to change it.

I find it finally. Took me nearly an hour!

Can you please share what you did?

Hi victor_viola,

You can right-click on the Class and select Formats….


Then edit formats in Formats dialog.
You can also Set as Default if you want the new formats become default.

Best Regards,

Roy.

Hi @roykeung ,
thank you so much for the information but I forgot to mention that I need to do this using the OpenAPI.

I am trying to implement a shape similar to a class shape but I am having trouble implementing the controller.
Do you have any tips about this?

Thank you and have a nice day.
