If you have ever paused while writing and wondered if it should be color or colour, the answer depends on the version of English you use. Both spellings are correct, but they belong to different regional standards.
In the United States, color is the accepted spelling. In the United Kingdom and many other countries that follow British English conventions, colour is preferred. This guide explains why the two spellings exist, where each one is used, and how to choose the right version for your audience.
Why Do Color And Colour Have Different Spellings?
Color and colour have the same meaning. The difference comes from the historical development of American and British English.
Quick Answer
Color is the standard American English spelling, while colour is the standard British English spelling. Neither is wrong. The correct choice depends on the audience, country, or style guide you follow.
The spelling colour came from older French influences on English. During the early years of the United States, American lexicographer Noah Webster promoted simplified spellings. As a result, many words ending in -our became -or in American English.
Some common examples include:
| American English | British English |
| Color | Colour |
| Honor | Honour |
| Favor | Favour |
| Labor | Labour |
