When a memory-resident application program of a Personal Computer (PC) is given control, it scans color registers, prior to displaying a menu, to determine the best match that it can find for the colors in which it wishes to display the menu. When a PC has a BIOS (basic input output system) with the ability to modify the color that will be displayed for a given attribute byte, each of the color registers may be modified from its default value. When a memory-resident application program of the PC is given control, it examines the contents of the color registers to determine if they have been modified from their default values prior to displaying any screen or menu. If the color registers have not been modified, the program uses its default attribute bytes to display the menu or screen in the desired colors.
