ABSTRACT:
A symbol generator that provides a video color signal that presents different colors for different portions of a symbol is illustrated herein. The symbol generator includes a number of separate stages that are connected in series to provide a processing pipeline. Elements for providing vertical color blends between the top of a symbol or selected background area and bottom of the symbol or background area are divided between the processing stages. Vertical color blending is achieved by mixing a difference color into a start color in an amount determined by the depth or displacement of consecutive raster lines from the top of the symbol.
