?bg and ?mask

In presetIcons icons are either rendered as icons with several colors or a single color. By default this is autodetected so icons look like they should. It is possible to override this autodetection by adding ?bg to make it a multi color icon or ?mask to make it a single color icon.

Try copying the <div> row and adding ?mask to the end of the icon class and also add text-red-300 to specify the color of the icon.
