What does HSL mean in color settings?
HSL is a way to describe colors using:
Hue (the base color, from 0–360° around the color wheel)
Saturation (color intensity, from 0% to 100%)
Lightness (how light or dark it is, from 0% to 100%)
Example: hsl(0, 100%, 50%) = pure red.
HSL is often easier to tweak than RGB because it separates color from brightness and intensity—useful in themes and design systems.
