TECHNIQUES TO MANAGE COLOR REPRESENTATIONS FOR A DIGITAL MAP
Techniques to manage color representations for a digital map are described. A method may comprise receiving category information having multiple categories defined for a geographic area of a digital map, each of the multiple categories having a category value. The method may further comprise selecting at least one color to represent two or more categories of the multiple categories. The method may still further comprise generating, by circuitry, an annotated digital map, the annotated digital map to comprise the digital map annotated with variations of the at least one color to represent the two or more categories of the multiple categories. Other embodiments are described and claimed.
