You can change the background color for individual shapes in data
diagrams to add visual interest or to convey conceptual groupings between
them.
To change the background color for shapes:
- Select a shape or a group of shapes.
- Click and click a color.
Tip: For Information Engineering (IE) notation diagrams,
you can also use the Properties page to semantically format colors based on
type, including view, table, implicit foreign key relationship, and foreign
key columns.
