For situations where using `--color` is not possible, add the environment variable `FORCE_COLOR=1` to forcefully enable color or `FORCE_COLOR=0` to forcefully disable.

The following two statements are equivalent: + +```js +console.log(chalk.bold.rgb(10, 100, 200)('Hello!')); +console.log(chalk`{bold.rgb(10,100,200) Hello!}`); +``` + +Note that function styles (`rgb()`, `hsl()`, `keyword()`, etc.) may not contain spaces between parameters. + +All interpolated values (`` chalk`${foo}` ``) are converted to strings via the `.toString()` method. All curly braces (`{` and `}`) in interpolated value strings are escaped. + + +## 256 and Truecolor color support + +Chalk supports 256 colors and [Truecolor](https://gist.github.com/XVilka/8346728) (16 million colors) on supported terminal apps. + +Colors are downsampled from 16 million RGB values to an ANSI color format that is supported by the terminal emulator (or by specifying `{level: n}` as a Chalk option). For example, Chalk configured to run at level 1 (basic color support) will downsample an RGB value of #FF0000 (red) to 31 (ANSI escape for red). + +Examples: + +- `chalk.hex('#DEADED').underline('Hello, world!')` +- `chalk.keyword('orange')('Some orange text')` +- `chalk.rgb(15, 100, 204).inverse('Hello!')` + +Background versions of these models are prefixed with `bg` and the first level of the module capitalized (e.g. `keyword` for foreground colors and `bgKeyword` for background colors). + +- `chalk.bgHex('#DEADED').underline('Hello, world!')` +- `chalk.bgKeyword('orange')('Some orange text')` +- `chalk.bgRgb(15, 100, 204).inverse('Hello!')` + +The following color models can be used: + +- [`rgb`](https://en.wikipedia.org/wiki/RGB_color_model) - Example: `chalk.rgb(255, 136, 0).bold('Orange!')` +- [`hex`](https://en.wikipedia.org/wiki/Web_colors#Hex_triplet) - Example: `chalk.hex('#FF8800').bold('Orange!')` +- [`keyword`](https://www.w3.org/wiki/CSS/Properties/color/keywords) (CSS keywords) - Example: `chalk.keyword('orange').bold('Orange!')` +- [`hsl`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsl(32, 100, 50).bold('Orange!')` +- [`hsv`](https://en.wikipedia.org/wiki/HSL_and_HSV) - Example: `chalk.hsv(32, 100, 100).bold('Orange!')` +- [`hwb`](https://en.wikipedia.org/wiki/HWB_color_model) - Example: `chalk.hwb(32, 0, 50).bold('Orange!')` +- `ansi16` +- `ansi256` + + +## Windows + +If you're on Windows, do yourself a favor and use [`cmder`](http://cmder.net/) instead of `cmd.exe`. + + +## Origin story + +[colors.js](https://github.com/Marak/colors.js) used to be the most popular string styling module, but it has serious deficiencies like extending `String.prototype` which causes all kinds of [problems](https://github.com/yeoman/yo/issues/68) and the package is unmaintained. Although there are other packages, they either do too much or not enough.
