RGB to HEX use cases
Convert RGB values to HEX when moving colors between design tools, CSS, brand guidelines, email templates, and image editors. HEX codes are compact and commonly used in CSS, while RGB values are often shown in color pickers, screenshots, and design handoff notes.
Color conversion tips
Check each RGB value is between 0 and 255, then copy the resulting six-character HEX code with the leading hash symbol for CSS. If the color is part of a brand palette, test it on both light and dark backgrounds and verify contrast before using it for text or buttons.
Accessibility note
A correct conversion does not guarantee readable contrast. Use a contrast checker before publishing foreground and background color combinations on important pages.
