Color or Colour: Which Is Correct?

Updated 2026-10-03 · Which One Is Correct editorial team

Quick answer: Both spellings are correct, but they belong to different regions. You should use color if you are writing for an American audience. If your readers are in the United Kingdom, Canada, or Australia, you must choose colour instead. This simple rule prevents errors.

The Short Answer

Color is the correct American spelling, while colour is the correct British spelling. You must choose based on your target audience to ensure your writing looks professional and consistent with regional standards.

People often confuse these spellings because major international brands and media outlets mix their usage. A global company might use the American version for marketing even in Europe, leading writers to believe that color is universally accepted everywhere.
