    Abstract: Mixed color effects in a character graphics display system are achieved by providing font characters comprising several character cells with different patterns which can selectively be read simultaneously to different color registers, thereby determining the color in which each character cell is to be displayed. The system also provides characters comprising only a single character cell which can selectively be directed to any of the color registers. A control system interprets color bits in a control word in accordance with the type of character being accessed.
