Farbe ändert sich in allen verzeichnissen

Hallo, wenn ich die Farben der Buttons bei formularen in verzeichnis a (für Webseite a) ändere, dann ändern sich die Farben auch bei Formularen in allen anderen Verzeichnissen b+c+d (webseite b+c+d) usw. 

wie kann ich nur jeweils farben für einzelne verzeichnisse ändern? Damit die Farben zu den jeweiligen Webseiten passen, danke.

Do you mean that when you change the color of one folder it also changes the colors of other folders?

It seems to be not happening on my end when I am trying to test this. Only one folder changes the color.

No, I mean the forms. I can change the color of the buttons in the forms. But I have made folders for different websites. And these different forms change the color immediately as soon as I change the color of a form. But I have a blue website, because I want to have the forms blue and I have a red website, because I want to have the forms red. I can not get on there.

My apologies, but the task is still not clear to me. I see you use forms with Cards layout mostly. So, you can change color for form buttons by changing or customizing a theme, for example:

On my side this does not seem to affect other forms. Could you provide some screenshots of the problem? Here is how you can post them: How-to-Post-Screenshots-to-Our-Support-Forum
