When a personal computer (PC) is connected to a host processor, its color palette is altered to provide intensified colors to support display of information coming from the host processor, which may be a mainframe computer or another PC, for example. When the PC functions with no host processor, a different color palette is provided. When a PC is connected to a host processor through a "hot key," which alternately switches between two programs with one being in the host processor and the other in the PC, a different color palette is employed because the host processor requires intensified colors. During the PC's initialization sequence, the lower eight color registers are initialized with eight colors and the upper eight color registers are initialized with the same eight colors intensified.
