What is the antonym of khaki?

There isn't a direct antonym for "khaki" in the sense of a color. "Khaki" is a shade of brown, and its opposite would be a color on the opposite end of the color spectrum.

However, depending on the context, you could use words like:

* Bright: If you're talking about the *intensity* of the color.

* White: If you're talking about a contrasting color.

* Dark: If you're talking about the *shade* of the color.

For example:

* "The room was painted a dull khaki, but I wanted something bright."

* "Her khaki pants were a stark contrast to her white shirt."

* "Instead of khaki, he wore a dark blue suit."

It's important to consider the context and what you're trying to express to choose the best word.
