# Color output controls

Buildx has support for modifying the colors that are used to output information
to the terminal. You can set the environment variable `BUILDKIT_COLORS` to
something like `run=123,20,245:error=yellow:cancel=blue:warning=white` to set
the colors that you would like to use:

Setting `NO_COLOR` to anything will disable any colorized output as recommended
by [no-color.org](https://no-color.org/):

> **Note**

> Parsing errors will be reported but ignored. This will result in default
> color values being used where needed.
