how to set color picker type for my widget field

Hi,
I am trying to include your nice siteorigin pagebuilder plugin into a theme that I am working on, but I could not find any instruction on how to set some field types such as color, icon and link selector to a widget.
So I am asking is it possible to provide me a sample of creating a widget with a field of color picker and icon please?
I know I am asking much but it really helps me a lot.

Waiting to hear back.
