A low saturation color scheme refers to a design using colors with reduced intensity, which tend to be less vibrant and more muted. These colors are often used to create a calm and soothing visual effect in design. In terms of color theory, low saturation colors are closer to grayscale, with less pigment and more white or black added to the base color to achieve the desired hue. This can be effective in balancing a composition and making other, more saturated colors stand out. In web design and graphic design, low saturation schemes are often used to maintain a professional and unobtrusive aesthetic.
