Lightweight color picker for X11. Use mouse cursor to select colors visible
anywhere on the screen to view their RGB representation.

### Installation

Currently, the easiest way to install xcolor is to use
[cargo](https://doc.rust-lang.org/stable/cargo/):

``` shell
$ cargo install xcolor
```

printed to the standard output. By default, color values will be printed in

| ---------------- | --------------------------------- | ------------------- |
| `hex`            | Lowercase hexadecimal (default)   | #ff00ff             |
| `HEX`            | Uppercase hexadecimal             | #00FF00             |
| `rgb`            | Decimal RGB                       | rgb(255, 255, 255)  |
