The HSL Color Model represents colors using three components: Hue, Saturation, and Lightness. Hue refers to the type of color, measured in degrees on a color wheel, ranging from 0° to 360°. Saturation indicates the intensity or purity of the color, while Lightness describes the brightness, ranging from black to white. This model is often used in graphic design and digital art because it aligns more closely with human perception of colors. By adjusting these three parameters, artists and designers can create a wide variety of colors and shades, making it easier to achieve the desired visual effects in their work.
