Large cities on a map are represented by what color?

Large cities on a map are represented by black. This color is commonly used to denote urban features, including significant locations such as cities, roads, and terrain features. The use of black helps to provide clear, distinct markings that stand out against other colors used for natural features like water and vegetation. Smaller features may be represented in other colors for differentiation, but major urban areas are typically marked in black to ensure visibility and ease of identification for navigational purposes.
