Colour or color means you are choosing between British and American spelling. “Color” is the standard spelling in American English, while “colour” is the standard spelling in British English and many Commonwealth varieties.
Have you ever written “colour” and then your spell checker changed it to “color”?
This happens all the time when people write for different countries. The word is simple, but the spelling can feel confusing. A student may learn colour in school, then see color on an American website. A blogger may write for UK readers, but their tool marks colour as wrong. A business owner may publish a product page and wonder which spelling looks more professional.
The good news is easy. Both spellings are correct. The right choice depends on your audience.
Use color for American readers. Use colour for British, Canadian, Australian, and many other Commonwealth readers. The meaning does not change. Only the spelling changes.
This guide explains colour or color in simple English. You’ll learn the difference, when to use each spelling, common mistakes, real examples, and how to keep your writing consistent.

The Origin / Background of Colour or Color
The spelling difference comes from regional spelling systems. British English often keeps “-our” in words like “colour,” “favour,” and “honour.” American English usually uses the shorter “-or” form, such as “color,” “favor,” and “honor.”
Cambridge’s English teaching blog explains that many words ending in -our in British English usually end in -or in American English. It gives examples like colour/color and labour/labor.
This spelling difference appears in many common words:
- colour / color
- favour / favor
- honour / honor
- labour / labor
- neighbour / neighbor
- behaviour / behavior
The meaning stays the same. The audience changes the spelling.
Oxford Learner’s Dictionaries lists colour with US English color, which shows the same regional split.
That is why neither spelling is “bad English.” They belong to different English spelling styles.

Common Mistakes With Colour or Color
Most mistakes happen when writers mix American and British spelling in the same article. Another common mistake is thinking one spelling is wrong. Both are correct, but each one fits a different audience and writing style.
| Mistake | Correction | Why It Happens |
|---|---|---|
| Mixing color and colour in one article | Pick one style | Writer uses sources from different regions |
| Writing colour for a US-only page | Use color | Audience is American |
| Writing color for a UK-only page | Use colour | Audience is British |
| Using colorful with colour | Use colourful | Related words should match |
| Using favorite colour in US style | Use favorite color | American and British spellings are mixed |
Mistake 1: Mixing spelling styles
Weak:
My favorite colour is blue, but this color looks better on the wall.
Better for US English:
My favorite color is blue, but this color looks better on the wall.
Better for British English:
My favourite colour is blue, but this colour looks better on the wall.
Mistake 2: Forgetting related words
If you choose colour, related words should usually follow British spelling too:
- colour
- coloured
- colourful
- colourless
If you choose color, related words should follow American spelling:
- color
- colored
- colorful
- colorless
Mistake 3: Letting spell check decide everything
Spell check depends on your language setting. If your tool is set to US English, it may mark colour as wrong. If it is set to UK English, it may mark color as wrong.
That does not mean the word is wrong. It means your spelling setting does not match your writing style.
