Color Legend in the Attribute Inspector

The color of an attribute value indicates if and in which form you can edit an attribute.

White: One or more files are selected in the Results list, and they have the same values.
Yellow: Multiple files are selected in the Results list, and their values differ.
Orange: Multiple files are selected in the Results list, with differing values, and they cannot be edited.
Red: One or more files are selected in the Results list, and their values cannot be edited.

Information on the meaning of the colors that are used in the Attribute Inspector is also displayed in a tooltip when you move the mouse pointer over one of the color icons below the Attribute Inspector.
