HSL: Hue, Saturation, Lightness
Hue, Saturation, Lightness (HSL) is a color representation that describes color by Hue (angle), Saturation (intensity), and Lightness (brightness).
HSL is helpful for building palettes and UI themes because it matches how designers often adjust colors, change hue slightly, reduce saturation, or tweak lightness for states and surfaces. It is still derived from RGB for display, so it does not expand what colors a screen can show.
Example
A primary blue might be HSL(210, 90%, 45%). A hover state could raise lightness to 52% while keeping hue and saturation stable.
Frequently Asked Questions
It is better for certain workflows like palette tuning and theme generation. For final digital output, RGB is what the display uses under the hood.
Because perceived brightness is not linear in HSL. Equal numeric steps can feel different across hues and saturation levels.
Hue is typically 0 to 360 degrees, where 0 is red, 120 is green, and 240 is blue.
It helps you generate consistent tints and shades, but you still must check contrast ratios against your background and text colors.
They differ in how the “brightness” channel is defined. Both are useful for UI tuning, but neither is perceptually uniform.
