Lighting, a very important part of modern life, is something we take for granted. We rarely consider how lighting affects our moods and well-being until we are faced with an inadequate light source or the wrong kind of light. Lighting can be categorized into four broad types: natural daylight, artificial daylight, artificial white light, and colored lighting. Natural daylight is provided by sunlight, and it has been found that natural sunlight can have positive effects on both physical and mental health. The indirect sunlight of a bright sky helps to balance out the bluer tones of shadows, making it less intense. Artificial daylight is a replica of natural daylight, made from fluorescent lights. It is often used in commercial spaces or in large homes because it can help improve the overall brightness of the environment. Artificial white light is also made using fluorescent lights and is commonly used indoors to provide illumination for tasks and activities. Colored lighting is produced by colored bulbs, which can come in a wide range of hues. Colored lighting is often used in certain areas to lend a certain atmosphere to the surroundings. It is popularly used in hospitality settings, where its use in combination with dim lighting can help to set a romantic mood. Lighting is an incredibly powerful tool, and understanding how it can be used to create the ideal atmosphere should be considered when creating any interior design or decor.
