| rgb(255, 87, 51) | |
| rgb(199, 0, 57) | |

B. An HSL code usually consists of three values: the hue (ranging from 0 to 360 degrees representing the color), saturation (0% to 100% indicating intensity), and lightness (0% to 100% indicating brightness).
| Color Sample | HSL Code |
|---|---|
| hsl(9, 100%, 60%) | |
| hsl(348, 100%, 39%) | |
| hsl(48, 100%, 50%) | |
| hsl(75, 70%, 75%) |
