Colours or Colors – Quick Answer

Both “colours” and “colors” are correct spellings.
The difference depends on the type of English you are using.

• Colours → British English
  Example: The artist mixed bright colours on the canvas.
  
• Colors → American English
  Example: The flag has three main colors.
  

The meaning is exactly the same. Only the spelling changes.

The Origin of Colours or Colors

The word comes from the Latin word color, which passed into Old French as colour. When English adopted the word, British English kept the French-influenced spelling colour with -our.

In the early 19th century, American lexicographer Noah Webster wanted to simplify English spelling. He believed shorter spellings were more logical and easier to learn. As a result, he promoted changes like:

• colour → color
  
• honour → honor
  
• favour → favor
  

These simplified spellings became standard in American English, while British English kept the original forms. That is why the difference exists today.

British English vs American English Spelling

British and American English follow different spelling rules for certain word endings, especially -our vs -or.

Key Rule

• British English: uses -our
  
• American English: uses -or
