The LCH color code stands for Lightness, Chroma, and Hue. It is a cylindrical representation of the CIELAB (LAB) color space, designed to be more intuitive for human understanding. 'Lightness' represents the brightness of the color, 'Chroma' indicates the intensity or saturation, and 'Hue' specifies the color itself (e.g., red, blue, green) as an angle on the color wheel. LCH is particularly valued in design and colorimetry for its perceptual uniformity, meaning that changes in numerical values correspond relatively well to visual changes perceived by the human eye.
A HSL color code, which stands for Hue, Saturation, Lightness, is a color representation system used in digital design and computing. Unlike RGB, which is based on the red, green, and blue primary colors, HSL focuses on different aspects of color.
HSL color codes provide a more intuitive and user-friendly way to work with colors, making it easier to adjust color attributes like hue, saturation, and lightness for various design purposes in web and graphic design.
