The story begins in the 1950s when engineers first described color as an additive mix of red, green, and blue light for television displays. Early analog systems could only combine three primary signals, but the principle established a universal language for representing hue that would later migrate into computer hardware and experimental graphic interfaces.
During the 1980s and 1990s, the rise of personal computing and the World Wide Web demanded a compact, platform‑independent notation. Hexadecimal codes—six‑digit strings derived from the same RGB values—were adopted by the W3C and quickly embedded in browsers, enabling designers to reproduce exact colors across disparate devices and paving the way for the modern practice of maximizing color impact.
