Let's try to find the nearest PMS color to Teelaunch's blue in hex:

pantone --hex 2A70AE

Or we could use the rgb values:

pantone --rgb 42,112,174

Output in table format on command line:

Dependency

1. Install npm module:

cd ~/project
npm install pantone

2. Require and lookup color:

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
