Environmental light refers to the natural illumination provided by the sun, moon, and stars, as well as artificial sources like streetlights and buildings. This light plays a crucial role in shaping our surroundings, influencing how we perceive colors, shapes, and textures in the environment. In addition to its aesthetic impact, environmental light affects ecosystems and human activities. For instance, plants rely on sunlight for photosynthesis, while urban areas often use artificial lighting to enhance safety and visibility at night. Understanding environmental light helps in designing spaces that are both functional and visually appealing.
