Web Color Codes: HEX, RGB, HSL, and CMYK

Web color codes workflows are most useful when they turn a color decision into a result that designers, developers, and content teams can reproduce. This guide explains web color notation, how to work with HEX, RGB, HSL, CMYK, named colors, or alpha values, and how to interpret consistent color values suited to CSS, design systems, and documentation. You will learn a reliable process for choosing the right notation for editing, sharing, conversion, and implementation, plus accessibility, responsive design, documentation, troubleshooting, and quality-control practices. The included ColorCraft conversion tools runs in the browser, provides immediate feedback, and avoids unnecessary uploads. Use the examples as a starting point, then verify every important value inside the actual component, theme, device, and production environment where people will experience it.
