“Colour” and “colour” have the same meaning, but they follow different spelling conventions. The main difference comes from regional English: colour is standard American English, while colour is standard British English and is also common in many other countries.
Understanding this small spelling difference can help you write accurately and consistently.
Definition of Color
Color is the American English spelling of the word used to describe the appearance of something based on how it interacts with light.
As a noun, color can describe a visual characteristic:
- The color of the sky is blue.
- I like the color of your shirt.
- Red is my favorite color.
As a verb, color means to give something a particular color or to change its appearance by applying color.
- The children colored the picture.
- She colored her drawing with crayons.
- The artist colored the background carefully.
The spelling color is especially appropriate when writing for readers in the United States or when following American English style.
Definition of Colour
Colour is the British English spelling of the same word. It has the same meaning and performs the same grammatical functions as color.
As a noun:
- What is your favourite colour?
- The colour of the leaves changed.
- Blue is a calming colour.
As a verb:
- The children coloured the pictures.
- She coloured the drawing with pencils.
- The designer coloured the background.
The spelling colour is commonly used in British English and in several other English varieties influenced by British spelling conventions.
Main Differences Between Colour and Colour
The biggest difference between color and colour is spelling rather than meaning.
Regional English
Color is the standard spelling in American English.
Colour is the standard spelling in British English and is widely used in countries and writing systems that follow British spelling conventions.
Meaning
There is no difference in meaning.
Both words can refer to:
- The appearance of an object
- A visual property caused by light
- A particular shade or hue
- A symbolic quality or characteristic
- The act of adding color to something
Pronunciation
In most varieties of English, color and colour are pronounced essentially the same way. The extra u in colour does not create a different pronunciation.
Verb Forms
The spelling difference continues when the word is used as a verb.
American English:
- color
- colors
- colored
- coloring
British English:
- colour
- colours
- coloured
- colouring
Related Words
The same spelling pattern appears in several related words.
| American English | British English |
| color | colour |
| colorful | colourful |
| colored | coloured |
| coloring | colouring |
| colorless | colourless |
| discolor | discolour |
This pattern is useful because once you know the regional preference, you can apply it to related forms.
Why Does Color Become Colour?
The difference has historical roots in English spelling. British spelling was influenced by French forms containing -our, while American English later developed spelling preferences that often removed the u from words such as colour.
Similar differences appear in other pairs:
- honor / honour
- favor / favour
- behavior / behaviour
- labor / labour
- neighbor / neighbour
American English generally prefers the shorter -or spelling in these words, while British English commonly retains -our.

Common Mistakes Learners Make
One common mistake is thinking that one spelling is correct and the other is incorrect. Both are correct in their appropriate English varieties.
Another mistake is mixing spelling systems within the same piece of writing.
For example, an American English article might use:
- color
- favorite
- center
- organization
Switching suddenly to colour can make the writing inconsistent.
A British English article might use:
- colour
- favourite
- centre
- organisation
The best approach is to choose one spelling system and follow it consistently.

- Both words have the same meaning.
- Both can be used as nouns and verbs.
- The extra u does not change the pronunciation.

Quick Tips for Writing and Speaking
When writing for an American audience, choose color.
When writing for a British audience, choose colour.
If you are writing an academic paper, website, business document, or professional article, check which English variety your audience expects.
In speech, you do not need to worry about the spelling difference because the two forms are normally pronounced alike.
For digital content, consistency is particularly important. If your website follows American English, use color throughout the relevant content. If it follows British English, use colour.
When to Use Each One
When to Use Color
Use color when:
- Writing in American English
- Targeting readers in the United States
- Following an American style guide
- Writing for an American school or organization
- Using American English software or editorial conventions
- Creating content specifically for a U.S. audience
Example:
The designer selected a bright color for the website button.
When to Use Colour
Use colour when:
- Writing in British English
- Targeting readers in the United Kingdom
- Following British spelling conventions
- Writing for many British-style educational contexts
- Using a publication that requires British English
- Maintaining a British English style throughout a document
Example:
The designer selected a bright colour for the website button.
When NOT to Use Each One
There is no situation where color is grammatically wrong simply because colour exists. Likewise, colour is not grammatically wrong simply because American English uses color.
However, you should avoid using the wrong regional spelling for your intended style.
For example, if your entire article follows American English, changing from color to colour without a specific reason creates inconsistency.
Similarly, if your document follows British English, randomly replacing colour with color may make the writing look inconsistent.
You should also avoid assuming that the spelling difference represents a difference in meaning. It does not.
Which One to Use (Decision Guide)
Choosing between color and colour is easy when you identify your audience.
Step 1: Identify your audience.
Are you primarily writing for Americans? Use color.
Are you primarily writing for British English readers? Use colour.
Step 2: Check your style guide.
If a school, employer, publisher, client, or website provides a preferred English style, follow it.
Step 3: Check surrounding words.
If you already use words such as favorite, center, and honor, you are probably following American spelling, so color is the natural choice.
If you use favourite, centre, and honour, colour is more consistent.
Step 4: Stay consistent.
Once you select one spelling, use it throughout the document unless you are quoting a source that uses another spelling.
