HSL breaks down color in a way that’s easier for us to understand. “Hue” refers to the type of color (like red, blue, green), “Saturation” controls how intense or faded the color is, and “Lightness” adjusts how bright or dark the color looks. This matches how we naturally think about colors.
In HSL, you can adjust one part of the color (like making it lighter or more saturated) without affecting the actual color (the hue). In RGB, changing one value (like red) can affect the entire color balance.
Unless you’re a master in RGB color theory, it’s hard to visualize the color without seeing it. For example, RGB (50, 30, 100) doesn’t immediately tell you what the color looks like. But in HSL, the same color (257°, 54%, 25%) gives more clues: Hue 257° is around the purple range, 54% saturation means it’s moderately vivid, and 25% lightness means it’s quite dark.
HSL is just easier to work with than RGB.
