Why should mariners pay attention to buoy colors?

Buoy colors are critical for safe navigation as they provide essential information about navigational hazards, safe channels, and other important maritime features. Each color conveys specific meanings under the U.S. Aids to Navigation System and internationally recognized standards. For example, green buoys typically indicate the left side of the channel when entering from open water, and red buoys signify the right side, thus helping mariners to navigate safely without straying into dangerous waters. Misinterpreting buoy colors can lead to grounding or collisions, making it vital for all mariners to be aware of the color codes for effective and safe navigational practices. This emphasis on safety is why the correct answer centers on the contribution of buoy colors to safe navigation.
