“Is it color or colour?” That is probably the question on your mind when autocorrect changes a spelling you are familiar with to something different.
The truth is, auto-correct is not entirely wrong; it is probably just your language setting.
The debate over the spelling is not strange. It is actually the doing of a dictionary writer who chose to give English spelling varieties.
Americans accepted this change, but the British decided they were fine with the spelling they had. However, this change has left the rest of the world second-guessing ever since.
Let’s jump in.
Key Takeaways
- Color is the American English spelling
- Colour is used in British English
- The spelling you choose should be based on your audience, not personal preference
What Is the Difference Between Color vs Colour?
There isn’t much difference between color vs colour. The only thing you would find separating both spellings is the letter ‘u.’
The difference is just the spelling, not the meaning. You can use both spellings to refer to the visual characteristics of things. Either spelling does not prevent a blue ball from changing its colour.
So if anyone walks up to you to ask, “color or colour which is correct?”

Your answer should be both, and the only thing that sets one apart from the other is the letter ‘u.’ It is not a matter of correctness; it is a matter of location.
- In the US, it is spelled as “color” (no “u”)
- In the UK, it is “colour” (with a “u”)
Meaning and Background
The word colour or color comes from the Latin word colōs, which means a ‘covering,’ ‘skin on boiled milk,’ or ‘appearance’. This Latin derivative made its way into Old French as ‘colur’, before finally settling into Middle English as ‘colour.’
No matter how you choose to spell it, color and colour mean the same thing. That is, the property of objects which we see as they reflect or emit light.
Whether you are talking to a friend of yours about a blue ocean or about yellow autumn leaves, you are speaking of the same thing.
The difference in the spellings is quite interesting. The purposeful alteration of American spellings to simpler and more phonetic ones was done by Noah Webster in the early 19th century.
Upon publishing his dictionary in 1828, Webster had different spellings of numerous words, such as colour, honour, favour, labour, as well as neighbour, but eliminated the letter u in them.
However, the British did not embrace the variations of the Webster dictionary. Although no meaning changed, they remained loyal to their traditional spellings.
When to Use Colour vs When to Use Color
People get confused when the “is it colour or color” question comes up. While it may seem confusing, there are several tips to help do away with the confusion surrounding the “is it color or colour” question.
This is how to know the right spelling to use:
Use Color when:
- You are writing for an American audience
- You are using an American English style guide like AP or Chicago
- You are submitting your work to a US-based company
Use Colour when:
- You are writing for people living in the United Kingdom, Canada, Australia, or New Zealand
- You are working with international organizations that use British English
- Your publication aligns with British English conventions
- You are writing academic papers for non-US institutions

Choosing the Right Spelling for Your Audience
There is a need to match your spelling with your audience when deciding on the appropriate spelling.
Some of the considerations to make when choosing the correct spelling include the following:
- Be familiar with your Analytics: Before you choose a spelling, try to find out where most of your readers live or which country reacts well to your content. For instance, if about 85% of your traffic comes from the US, you should know that spelling with ‘u’ is wrong.
- Be sure which your Client Prefers: It is not always up to you, and particularly when you are writing for someone. Remember to ask them and determine the best style guide that suits them.
- Stay on Course: When you have decided on the correct decision to make with your client, remain with it. One of the things that makes you look unprofessional is when you are interchanging between spellings.
So, before you publish or send in that work, ask yourself
- Who is reading this?
- Where are they located?
- Is this academic, casual, or professional?
These questions are important, especially if you are trying to decide which to rank, color or colour in USA. The appropriate selection of spelling helps provide visibility to your work.
Common Mistakes to Avoid
The pitfalls to watch out for when using colour or colour are as follows:
- Concluding that there is a wrong Spelling: The one error that you will make is to assume that since one of the spellings is right, then automatically the other spelling is wrong. Both spellings are right, and the fact that you add or leave out u does not matter.
- Confusion of Spellings Within the Same Paper: This is a very common mistake. Sometimes it is not your fault. You may start with ‘colour’ and auto correct changes it to ‘color halfway through. The best way to prevent this is by doing a final check.
- Forgetting Related Words: Always remember that there are other variations of color/colour. So if you choose ‘colour’ for instance, you also have to use the same thing when spelling, ‘colourful,’ “colourless,” and “colouring.” Always stay consistent with the whole word family.
- Ignoring your Spell-Checker Settings: Even if you use the right spelling and your spell checker is not set to the right English region, you might be wasting your time. You will just realise that you are clicking “ignore” on the correct words.
- Using British spelling for American Publications or Vice Versa: To avoid this, always check the publication’s style before submitting.
