The color of intermediate contour lines on a standard topographic map is which color?

• A. Light Brown
• B. Dark Brown
• C. Green
• D. Blue

Answer: (A)

On standard topographic maps, elevation is shown with contour lines drawn in brown. The lines that are darker are the index contours (every fifth line) and they are labeled for easy reading. The lines in between, the intermediate contours, are drawn in a lighter shade of brown to provide a finer gradation of elevation without making the map feel cluttered. Blue indicates water features and green indicates vegetation, not elevation. So the intermediate contour lines are light brown.
