[![Build Status](https://travis-ci.org/bgrins/TinyColor.png?branch=master)](https://travis-ci.org/bgrins/TinyColor)
## Including in node
`tinycolor` can be installed from npm:
npm install tinycolor2
Then it can be used in your script like so:
```js
var tinycolor = require("tinycolor2");
var color = tinycolor("red");
```
Or in a module like so:
```js
import tinycolor from "tinycolor2";
var color = tinycolor("red");
```
## Including in a browser
Download [tinycolor.js](https://raw.githubusercontent.com/bgrins/TinyColor/master/tinycolor.js) or install it with bower:
The package can be bundled from npm, but if you prefer to download it locally you have two choices:
bower install tinycolor
### ESM
Then just include it in the page in a `script` tag:
It can be used as a module by downloading [npm/esm/tinycolor.js](https://github.com/bgrins/TinyColor/blob/master/npm/esm/tinycolor.js) or using https://esm.sh/tinycolor2.
```html
<script type='text/javascript' src='tinycolor.js'></script>
<script type='text/javascript'>
<script type='module'>
import tinycolor from "https://esm.sh/tinycolor2";
var color = tinycolor("red");
</script>
```
## Including in node
`tinycolor` may also be included as a [node](http://nodejs.org/) module like so:
### UMD
npm install tinycolor2
You can use it directly in a script tag by downloading the UMD file from [npm/cjs/tinycolor.js](https://github.com/bgrins/TinyColor/blob/master/npm/cjs/tinycolor.js):
Then it can be used in your script like so:
```js
var tinycolor = require("tinycolor2");
```html
<script type='text/javascript' src='tinycolor.js'></script>
<script type='text/javascript'>
var color = tinycolor("red");
</script>
```
