Converts color references to the shortest equivalent.

Colors can be represented in various notations, the following table showcases some equivalent colors:

| Name     | rgb()              | #rrggbb   | #rgb   |
| -------- | ------------------ | --------- | ------ |
| `red`    | `rgb(255, 0, 0)`   | `#ff0000` | `#f00` |
| `orange` | `rgb(255, 165, 0)` | `#ffa500` |        |
| `yellow` | `rgb(255, 255, 0)` | `#ffff00` | `#ff0` |
| `green`  | `rgb(0, 128, 0)`   | `#008000` |        |
| `blue`   | `rgb(0, 0, 255)`   | `#0000FF` | `#00f` |
| `purple` | `rgb(128, 0, 128)` | `#800080` |        |

It makes no difference which format is received by a client, and each one has wide support across browsers and image viewing software.
