Abstract
A navigation system includes a display displaying a map of roads from a road database. The navigation system utilizes a palette of colors to display the road and background on the display. The palette preferably includes a plurality of shades for each of a plurality of colors to be displayed including the background color and the road color. The roads on the display are preferably anti-aliased by indexing a different intensity of the shade of the object based upon the relative position of the pixel and an ideal object area.
