"BRIGHTEN" refers to the act of making something lighter or more vivid. This can apply to colors, such as brightening a painting by adding lighter shades, or to moods, where a cheerful event can brighten someone's day. The term is often used in various contexts, including art, photography, and emotional well-being. In the context of lighting, brightening can involve increasing the intensity of light in a space, making it feel more open and inviting. This can be achieved through natural light, such as sunlight, or artificial sources like LED lights and lamps. Brightening enhances visibility and creates a more pleasant atmosphere.
