Why have my custom colour settings all changed?

I set all the colours to a custom theme on my order form to tie in with my brand but the have ll changed for no reason? Please can you tell me how to change them back to how they were without having to tediously do them all seperately.

thanks

May I suggest using the revision history tool, a tool that reviews older version of your form and reverts it back.

Just select your form and on the right side click More,select Revision History

Here is a related article you can check.How-to-View-Form-Revision-History

If the issue still remains, can you give us the FormID and the colors that was changed, so we can check it further.

Let us know how it goes.
