What color is used to depict Class E airspace on aeronautical charts?

Class E airspace is depicted on aeronautical charts using shaded magenta or blue colors. This representation helps pilots quickly identify areas of Class E airspace, which is a controlled airspace that can extend from the surface upward or from a specified altitude. The shaded magenta indicates airspace that begins at a specified altitude, while blue may indicate areas where the Class E airspace starts at the surface. This coloring system is designed to provide clarity and quick recognition for navigation and situational awareness. Understanding these distinctions is crucial for pilot safety and adherence to airspace regulations, as they ensure pilots can effectively plan their routes and manage their altitude in relation to controlled airspace.
