How to change or remove rainbow colored border?

How to change or remove the Rainbow colored border (border-wrap-color ?) for the template?
Is the only way to create a custom CSS (if yes, exactly how and where) or can I simply change the actual source (image?)
I first looked in the JA Rights documents and all through this Forum.
Thanks!

joomlaexcel Hi

It's background color set for the wrapper:

div.t4-wrapper {
    background: linear-gradient(to right,#ea533d,#f49a22,#abaf27,#50ab47,#189a95,#0286e6,#306fe2,#5061dc,#7a4ed3);
    animation: rainbow 18s ease infinite;
}

You can override this CSS rule.
