Both HSL and HSV describe color using hue, but they define brightness differently. This converter maps HSL's Lightness axis to HSV's Value axis, which is how most interactive color pickers work.

HSL describes colors using Hue (0°–360°), Saturation (0%–100%), and Lightness (0%–100%). Designers favour it because adjusting a single axis — making a color lighter or more vivid — is intuitive.

HSV (Hue, Saturation, Value) is the model most color pickers use internally. Value represents brightness from black to full color, which aligns closely with how we perceive color intensity.

Handy when porting color values between design tools that use HSL (like CSS) and applications that use HSV (like Photoshop's color picker).
