This tool adjusts the saturation of all colors in the image evenly, regardless of their initial saturation level. Increasing saturation enhances the richness and vividness of colors, making them appear more vibrant. Conversely, decreasing saturation tones down the intensity of colors, resulting in a less vivid appearance. It's important to avoid excessive saturation, as it can make the image look unnatural and overly vibrant. Finding the right balance ensures colors look appealing and true to life.
