You may have seen grayscale and greyscale and felt unsure which one is correct.
Many designers, photographers, developers, students, and writers face this same confusion.
The words look almost the same, so it is easy to wonder if one is wrong or if both are acceptable.
The confusion exists because English spelling changes by region. American English uses gray, while British English uses grey.
People search for “grayscale or greyscale” to get a clear answer and avoid mistakes.
This guide explains which spelling is correct, where each one is used, and how to choose the right option for your audience so you can write with confidence every time.
Grayscale or Greyscale: Quick Answer
Both grayscale and greyscale are correct spellings.
- Grayscale is used in American English
- Greyscale is used in British English
They mean the same thing: a range of shades from black to white, without color.
Examples:
- US English: Convert the image to grayscale before uploading.
- UK English: The photo appears clearer in greyscale.
The spelling depends on regional language rules, not meaning.
The Origin of Grayscale or Greyscale
The word comes from two parts:
- Gray/Grey – a color between black and white
- Scale – a range or gradient
The difference between gray and grey goes back centuries. Both spellings existed in Old English and Middle English. Over time, regional preferences developed.
When English split into American and British standards:
- American English settled on gray
- British English preferred grey
When the compound word formed, it followed the same rule:
- Grayscale = American spelling
- Greyscale = British spelling
Technology later made the word more common, especially in photography, printing, film, and digital displays. Despite modern usage, the regional spelling rule stayed the same.
British English vs American English Spelling
The difference is simple and consistent.
Core Rule
- American English: gray → grayscale
- British English: grey → greyscale
Examples in Context
- American: The camera shoots in grayscale mode.
- British: The magazine uses greyscale images.
