In first and second modes, successive pairs of bytes, each with a suitable number (e.g. 8) of binary indications, are respectively processed in each clock cycle or clock half cycle to provide a true color. In these modes, the successive pairs of bytes may be processed in a 5,5,5, or a 5,6,5 pattern representing the primary colors for a pixel. In a third mode, the bytes may be introduced to a memory having a plurality of positions for storing individual binary combinations, which may be updated by a microprocessor, representing pseudo colors. In the third mode, a particular position in the memory is selected in accordance with the indications in each byte in each clock cycle or half cycle. In an additional mode, three successive bytes in a group may indicate the primary colors defining a true color when the fourth byte in the group provides a particular indication (e.g. 0 for all 8 binary bits). In this mode, indications in the fourth byte other than the particular indication select a particular position in the memory to represent a pseudo color. In this mode, the successive bytes may be respectively provided either in each clock cycle or clock half cycle. The binary indications representing the true color or the pseudo color in the different modes are converted to analog signals for introduction to a video monitor. In the additional mode, the indications in particular positions in the memory may be blocked from conversion to analog signals.
