The colorpicker element is a nice way to let the user input any color.
When the element is present in a section, the user will have a nicely formatted colorpicker to choose a color. This color will be saved in hex format. For example: #ff0000.
In the view file, this element is accessible by its name, for example
<a style="color:<?=$text_color;?>">A nice colored text</a>
<a style="color:#ff000">A nice colored text</a>
