(Hue, Saturation, Lightness).
- Development: Proposed by computer graphics researchers in the 1970s as an alternative color representation to RGB that is more intuitive for human perception.
- Colors/Units of Measure: Hue (the type of color), Saturation (the intensity of the color), Lightness (the brightness of the color).
- Hardware-Based: Primarily used in software applications for color selection, image editing, and web design.
- Year of Release: HSL was proposed in the 1970s as a way to represent colors in a more intuitive manner.
- Founding Institution: Proposed by computer graphics researchers; standardized by various organizations such as W3C.
- Color Theory: HSL is based on the way humans perceive color. Hue represents the type of color (e.g., red, green, blue), saturation represents the intensity of the color (from dull to vibrant), and lightness represents the brightness of the color (from dark to light).
- Color Model: Cylindrical representation of color.
- Total Number of Possible Color Combinations: Infinite range of colors, covering the entire visible spectrum.
- Primary Colors: Hue.
- Secondary Colors: Saturation and Lightness.
- Tertiary Colors: Not applicable.
