Color reduction is a process used in digital imaging to decrease the number of colors in an image. This technique helps to simplify images, making them easier to store and process. By reducing colors, images can maintain their essential features while using less data, which is particularly useful for web graphics and applications. In color reduction, algorithms analyze the original image and select a limited palette of colors that best represent the image. Common methods include quantization and dithering, which help to create visually appealing results even with fewer colors. This process is widely used in graphic design and computer graphics.
