What color on a topographic or orienteering map indicates forests with little or no undergrowth for easy passage?

The color that signifies forests with little or no undergrowth, allowing for easier passage, is white. This color typically represents areas that are forested but do not have dense underbrush, making navigation and movement more straightforward. In the context of topographic and orienteering maps, the representation of different land cover types through colors helps users understand the landscape features and plan their routes effectively.

On the other hand, green usually denotes densely forested areas with substantial undergrowth, making travel more difficult. Yellow is often used to indicate open areas, such as fields or grasslands, where vegetation is minimal, while brown typically signifies elevation changes or contour lines, indicating terrain features like hills or mountains rather than specific vegetation types. Understanding the meanings of these colors is crucial for effective navigation in outdoor activities.
