Step-by-step explanation:
Color vision is the ability to perceive and differentiate between various colors. This ability is present in many animals, including humans. Color vision serves humans by allowing us to see and distinguish different objects and their characteristics based on their color. The human eye contains specialized cells called cones that are responsible for color vision. There are three types of cones, each sensitive to different wavelengths of light: red, green, and blue. When light enters the eye, these cones send signals to the brain, which then processes and interprets the information to perceive color. Color vision is important for many aspects of daily life. It helps us navigate the world by distinguishing between different objects, identifying potential dangers, and enhancing our perception of beauty and aesthetics. For example, color vision allows us to recognize traffic lights and determine whether they are red, yellow, or green, which is crucial for safe driving.
