## Pick & click

### Instructions

Today, you're gonna create your own color picker.

Write the function `pick` which creates a `hsl` color picker varying the `hue` and `luminosity` of the according to the position of the mouse, which:

- changes `background` of the `body`
- displays those 3 values, using the `text` class:
  - the `hue` value in a `div` with the class `hue`
  - the `luminosity` value in a `div` with the class `luminosity`
  - the full `hsl` value
- copies that value in the clipboard on click
- displays two SVG lines, with respective ids `axisX` and `axisY`, following the cursor
