Many writers wonder whether they should use color or colour. The answer depends on the type of English you are using. Color is the standard spelling in American English, while colour is the standard spelling in British English.
Both words have the same meaning. They refer to a visible shade, hue, or appearance created by light. For example, red, blue, green, black, and white are all colors or colours, depending on your spelling style.
The main difference is not grammar or meaning. It is regional spelling. If your readers are in the United States, use color. If your readers are in the United Kingdom, Australia, New Zealand, or most British-style English regions, use colour.

Why Are the Spellings Different?
The spelling difference comes from the history of English.
The word colour came into English through French influence. British English kept the older spelling with u.
American English later adopted shorter spellings for many words. Noah Webster, an American dictionary writer, supported simplified spellings. His work helped forms like color, honor, favor, and labor become standard in the United States.
That is why American English often drops the u, while British English keeps it.
