How do you change a colors value?

To change a color's value, you can adjust its hue, saturation, and brightness using color models like HSL (Hue, Saturation, Lightness) or RGB (Red, Green, Blue). For example, in HSL, you can increase or decrease the lightness to make a color lighter or darker. In RGB, altering the intensity of the red, green, or blue components will shift the color's value. Various design and image editing software tools also provide sliders for these adjustments, making it easy to manipulate color values visually.
