  1. Identify which notation your tool shows.
  2. Convert RGB → HEX for most CSS tokens.
  3. Convert HEX → RGB for canvas APIs that want channels.
  4. Store a single source of truth in your design system.
  5. Recheck contrast after any conversion-based tweaks.

Why it matters

Teams ship mismatched buttons when someone pastes the wrong notation.

Tips

  • They are not different colors—just different encodings.
  • CMYK is the odd one out because it targets print.
  • Prefer 6-digit HEX in shared docs to avoid ambiguity.
