Color in a character interface differs from color in a graphical interface in these ways:

• In character interfaces, the BGCOLOR and FGCOLOR attributes have the unknown value (?).
• Each location in the color table contains a foreground/background color pair.
• DCOLOR specifies a foreground/background color pair that a widget uses when it displays data.
• PFCOLOR specifies a foreground/background color pair that a widget uses when it prompts for data.

When designing your interface, make sure that you specify different color pairs for DCOLOR and PFCOLOR.
