Hi,
Is there a way to reset a field value to its default in the panel. For example a resetting a color picker to its default value.
No, unless you manually pick the default value. There is no such thing as a reset button.
What you could do to make things easier, is to mark the default value as default, so users know what the default is (if you use a color set)
An alternative would be a custom color field implementation with a reset button. Don’t know how easy or difficult it would be to set this up by extending the field.
I set the defaults as a color set as a basic workaround.
