CIELCHvärijärjestelmiä

CIELCHvärijärjestelmiä are color spaces that describe colors based on lightness, chroma, and hue. CIELCH is derived from the CIELAB color space and uses cylindrical coordinates instead of Cartesian coordinates. Lightness (L*) represents the perceived brightness of a color, ranging from 0 (black) to 100 (white). Chroma (C*) quantifies the intensity or saturation of a color, with higher values indicating more vivid colors. Hue (h°) represents the color itself, such as red, green, or blue, and is typically expressed as an angle in degrees from 0 to 360.

The CIELCHvärijärjestelmiä, specifically CIELCh, offers a more intuitive way to understand and manipulate color compared to CIELAB. For example, changing the chroma directly alters the saturation of a color without affecting its perceived lightness or hue, which can be advantageous in color correction and design applications. Hue is measured as an angle, where 0° is often red, 90° yellow, 180° green, and 270° blue, though the exact starting point can vary depending on the implementation. Understanding the relationship between these three components allows for precise control and consistent color reproduction across different devices and media.
