convert given hex color (with or without
#sign) to the xterm color. If there is no exact match, search for the closest one. - rgb2xterm(r, g, b): convert given rgb color (passed tot he method as 3 separate parameters) to the xterm color. If there is no exact match, search for the closest one.
How to use?
Install simply with:
bash
npm install color2xterm
Then in your code:
```javascript
var c2xterm = require('color2xterm');
c2xterm.hex2xterm('#ffffff'); // result: 15
c2xterm.rgb2xterm(255, 255, 255); // result: 15
// Find closest color:
c2xterm.hex2xterm('#0DADD6'); // closest color is #00AFD7 so the result is 38
