What does the color red indicate on a map?

On a map, the color red typically identifies major roads and highways, helping users easily locate significant transportation routes. This use of red is standard in many mapping conventions, where it stands out against other colors and provides clear visual guidance for navigation and planning. Major roads are crucial for understanding travel routes and accessibility within the mapped area.

Other colors are designated for different features; for example, blue is commonly used for water bodies, green for vegetation, and various shades or patterns may represent contour lines or elevation changes. Understanding the color-coding on maps is essential for effective interpretation and use of the information presented.
