Display ColorsKeyCreator \ File \ Properties \ Display-Colors
The Display Colors pane of the Properties function contains the settings which allow you to customize the colors of your display for each part. The color palette is also available from this dialog.
Background - This setting allows you to set a color attribute for the Layout and Model mode backgrounds in all viewports. Top and Bottom input fields are provided that allow you to create a gradient background (one color fades to the other). If you want a solid background, the same color must be chosen for both Top and Bottom. Use the Direction arrow setting to alter the direction of the color gradient, useful in perspective visualization and in presentations. Note that flipping colors 1 and 2 effectively changes the arrow direction (see below.)
Note: If you do not set attributes (all existing instances and the default for new instances), then KeyCreator uses the Instance Border color and, except for Detail Callouts, uses a dashed border. (For Detail Callouts, KeyCreator uses a solid border.)
