Historical Context

The RGB color model dates back to early color television and electronic display systems, where red, green, and blue light were combined to reproduce visible colors. HEX notation emerged alongside the development of HTML and CSS in the early web era, offering a compact base-16 representation of RGB values. Today, both formats remain foundational in digital imaging, display technology, and web standards.
