Which color represents industrial utilities on a land use map?

• A. Yellow
• B. Brown
• C. Blue
• D. Gray

Answer: (D)

Color coding on land use maps is designed so you can read the map at a glance, with each color representing a type of land use. Gray is used for industrial utilities because it signals built infrastructure—factories, power facilities, warehouses, and utility corridors—without implying residential or natural features. It also contrasts well with colors like yellow (residential), green (parks/open space), and blue (water or sometimes transportation), making the industrial/utility category stand out clearly. While map schemes can vary, gray has become a common, neutral choice for these uses because it’s easy to reproduce and distinguish in different contexts.
