Color codes are fundamental to web design and digital media. Whether working with HEX values from a design tool or RGB values from a stylesheet, converting between formats helps designers and developers compare a visual choice with the exact value used in code. This converter provides a live preview, input validation, and support for shorthand HEX values while processing the conversion locally in your browser.
The tool expands 3-digit shorthand HEX codes to their 6-digit equivalents, checks that RGB components are within their valid range, and shows the resulting color for a quick visual check. The conversion is useful when documenting design tokens, reviewing a palette, or moving a color between a design specification and CSS. For production work, still test the chosen color against its real background and check contrast for the people who will use the interface.
HEX (hexadecimal) uses 6 characters to represent color: #RRGGBB where RR, GG, BB are red, green, blue values in base-16. Most common in CSS, web design, and digital tools. Compact and widely supported.
RGB lists decimal values (0-255) for red, green, and blue components. Format: rgb(R, G, B). More intuitive than HEX for understanding color composition. Used in CSS, design tools, and programming.
Shorthand like #ABC expands to #AABBCC by doubling each character. Only works when hex digits repeat pairs. This converter automatically expands shorthand to full format for accuracy.
Display calibration, color space assumptions, and monitor settings affect perceived color. The numerical values are identical; appearance varies by device. Always test colors on target devices.
