Abstract: The invention provides a method of controlling the color of the individual pixels of a digital display with appearance information formed by color information and position information. Each set of color information is applicable to a pair of adjacent pixels, but the position signal may cause the color signal of one pair of pixels to control the color of one pixel of the adjacent pair. Apparatus for practicing the invention includes a storage means capable of storing two sets of appearance information at the same time and for selecting one set of information or the other for application to the display.
