ABSTRACT:
A color display system has a color encoder which receives intensity signals via a video generator from a graphics generator as well as color signals. The color encoder processes the color and video signals for transmission to a display monitor which then displays the graphics in color. Such a system is provided with apparatus for selecting from a palette set of colors a working subset of the color signals for use in the display of colored graphics. The apparatus includes a palette memory for storing sets of groups of indicia wherein each of the groups of indicia represents a different color signal of the set. Means are provided for sequentially transferring the groups of indicia from the palettememory to the display monitor for displaying the colors associated with the groups. A working memory stores a subset of groups of indicia. Selection means transfer from the palette memory to the working memory groups of indicia in accordance with the desired colors displayed on the display monitor.
