## Install
```bash
npm install -g pantone
```
## CLI
Let's try to find the nearest PMS color to [Teelaunch's][2] blue in hex:
```bash
pantone --hex 2A70AE
```
Or we could use the rgb values:
```bash
pantone --rgb 42,112,174
```
Output in table format on command line:
```bash

## Dependency
**1.** Install npm module:
```bash
cd ~/project
npm install pantone
```
**2.** Require and lookup color:
```js
var pantone = require('pantone')
// rgb usage
pantone({ r: 42, g: 112, b: 174 }, rgbCallback)
function rgbCallback(err, results) {
if (err) throw new Error(err)
console.log(results)
}
// hex usage
pantone({ hex: '#2A70AE' }, hexCallback) // you can also use `rgb` instead of `hex`
function hexCallback(err, results) {
if (err) throw new Error(err)
console.log(results)
}
```
## Proxy settings
For all of you who are behind a proxy server we are using the `process.env` property from node to take the value from `HTTP_PROXY` or `HTTPS_PROXY` in order to make the call to the server. This means that you need to set those properties as environment variables (it's a good thing anyways because lots of other apps are using this property).
### Windows
1. Right-click My Computer, and then click Properties.
2. Click the Advanced tab \ Advanced system settings.
3. Click Environment variables.
4. Under `System variables` Click New to add a new variable name and value.
5. Variable name: `http_proxy`
6. Variable value: `http://proxy-server.mycorp.com:8080` (replace the value with your details, the general syntax is: `http://username:password@proxyhost:port/ `)
7. Click OK and save your changes
Now if everything went down OK you should be able to use Pantone.
### Ubuntu (various Linux distributions)
> Notice: I tested this on a VM locally and worked perfectly but might not work for you depending on various factors, so if you have more knowledge please submit a pull request, or let us know and we can update this readme file.
If you want to use a proxy server only once in one terminal window use this command:
`export http_proxy=http://proxy-server.mycorp.com:8080`
If you want a more permanent solution:
Put the environment variable into the global `/etc/environment` file:
`http_proxy=http://proxy-server.mycorp.com:8080`
Execute `source /etc/environment` in every shell where you want the variables to be updated:
`$ source /etc/environment`
Check that it works:
$ echo $http_proxy
$ http://proxy-server.mycorp.com:8080
