High angular tolerant subtractive structural color filters with improved color purity, employing a plasmonic perfect absorption property, are demonstrated. The proposed devices exhibit angle‐insensitive characteristics up to ±80° while maintaining both intensity and bandwidth. This approach has potential for a wide variety of applications, such as color display devices and image sensors.
