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.
RGB color code, short for Red, Green, Blue color code, is a numerical representation used in digital design and computing to define colors. It consists of three numerical values, each ranging from 0 to 255, representing the intensity of the red, green, and blue primary colors. By adjusting these values, a wide spectrum of colors can be created. RGB color codes are commonly employed in various applications, including web design, graphic design, and image editing, to precisely specify and reproduce colors for digital displays, images, and content.
