### **Environment**:

Your OpenProject Version: 10.4.0 / Self hosted enterprise Edition

### **Steps to reproduce:**

1. Go to page Design
2. Change color schema
3. Click save
4. Your custom color schema is lost/gone

### **Actual Behavior**

Cannot go back to previous color schema

### **Expected Behavior**

1. Get a Warning, that every custom changes will be lost. Begin of the deletion
2. Can save your custom color schema with a name and come back later to it

Anyway: Is there a possibility to get my previous settings back?

Thanks and kind regards,
HaraldEnd of the deletion
