Planning the Colors in a Worksheet

The color that is assigned to a label displays in the background whenever the name of the label appears at the top of a window. The lettering is displayed in a color that is computed by the window system to complement the background. In our example, the security administrator chooses to keep the colors already assigned to the administrative labels in the default label_encodings file. The administrator assigns green to PUBLIC, yellow to INTERNAL_USE_ONLY, blue to labels that contain NEED_TO_KNOW (with different shades of blue assigned to each compartment), and red to REGISTERED, as shown in the following table.
