How to reset value

Spectrum widget - has widget settings with Empty color

I'm also looking for a option like this...when I use the option to have multiple colors in one field (multi value field) I also want to be able to remove colors. When using the HTML 5 widget which is the best accessible one (Spectrum can't be used using the keyboard) I'm not able to empty the field is there some kind of work around or way to solve this? Is there a remove item buttons just like there is an add item button.

The HTML5 widget in this module doesn't allow for an empty selection. Once a color is chosen and saved, it becomes the default value. This means that leaving the color picker empty is not supported, and it inherits the default color set.
Unlike the color picker, the Spectrum widget is actually a text field which allows users to leave the field empty, providing an option for no color selection.
Additionally, to address the challenge of removing items when the field is set to multi-valued, I've prepared a patch that adds a remove button. This patch is applicable until Drupal version 10.2.2. It's worth mentioning that in Drupal 10.2.2, the core fixes the mentioned bug, and the remove button is already available.

I have reviewed and applied patch #6, and it resolved the issue for the multi-value field in Drupal 9.5.0. The patch provided a button to remove items when the field is set to multi-valued, as described in comment #6. See the attached image.
It can be moved to RTBC.
