Both colour and color are correct spellings of the same word. Color is used in American English, while colour is the standard spelling in British English, Canada, Australia, New Zealand, and many other Commonwealth countries.
Have you ever typed colour into a document only to see your spell checker underline it in red? I remember writing an article for a U.S. client after spending weeks working with British publications. Without thinking, I wrote colour throughout the entire piece. The editor politely asked me to change every instance to color. That small difference reminded me how one extra letter can matter depending on your audience.
This is one of the most searched spelling questions in English. Since both versions appear online, in books, and in everyday writing, many people assume one must be wrong. The truth is much simpler.
The difference between colour and color isn’t about grammar or meaning. It’s about regional spelling conventions. Once you know which countries use each version, you’ll never second-guess yourself again.
In this guide, you’ll learn the history behind both spellings, discover when to use each one, compare real-world examples, and avoid common mistakes.

How to Pronounce Colour and Color
The pronunciation is almost identical in every major variety of English.
Color
Pronunciation: /ΛkΚl.Ι/
Phonetic spelling: KUL-er
Colour
Pronunciation: /ΛkΚl.Ι/
Phonetic spelling: KUL-uh
The spelling changes, but the pronunciation is nearly the same. Most listeners won’t notice any difference.
Quick Tip
The extra “u” in colour changes the spelling, not the meaning or pronunciation.
The Origin and Background of Colour or Color
Both spellings come from the same Latin word, color, meaning color, appearance, or hue.
The word entered English through Old French as colour, which is why British English still keeps the “u.”
In the early 1800s, American lexicographer Noah Webster introduced spelling reforms to simplify American English. He removed silent letters from many words to make spelling more consistent.
As a result:
- colour became color
- favour became favor
- honour became honor
- labour became labor
These simplified spellings became standard in the United States, while Britain and many Commonwealth countries continued using the original forms.
Today, both spellings are officially correct. The best choice depends entirely on your audience.
