Is There a Difference Between Grey and Gray?

Both grey and gray refer to the same color, which is between black and white. The only difference is spelling.

The distinction is based on regional usage, not meaning. Neither spelling is more correct than the other. The right choice depends on the English dialect you are using.

When Do You Use “Gray”?

Use gray when writing for an American English audience. This applies whether you are describing a color, writing a phrase, or using word variations.

When Do You Use “Grey”?

Use grey when writing for a British English audience or for countries that generally follow British spelling conventions, such as Ireland, Australia, and Canada.

If you are writing an essay, journal article, or professional document for a British institution, grey is usually the preferred spelling.

British English Examples

• The sky was a pale, uninteresting grey.

Common British English Variations

Words Usually Spelled “Grey”

• Greyhound
• Earl Grey
• Lady Jane Grey
• Grey matter

Words Usually Spelled “Gray”

• Gray whale
• Asa Gray
• Gray’s Anatomy

For example, even if you are writing in British English, you should write gray whale, not grey whale, because that is the standard spelling of the term.

How Do You Remember Which Spelling to Use?

The easiest way to remember the difference is:

• Gray has an A, which stands for American English.
• Grey has an E, which stands for England.

So, if you are writing for an American audience, use gray. If you are writing for a British or British-style audience, use grey.

Does the Spelling Change in Word Variations?

No. Variations of the word should follow the spelling of the original word.

If you use gray, then use:

• Grayish
