Design approach to update and define background color #19
Description
Story:
As a user I would like the ability the define and update the background color of a patch, specifically when the grid arrangement doesn't take up the full space.
Other notes:
Currently default is a backend solution to defining a rectangle at the beginning of the creation.
Extension: this could also connect with text elements and the background used for them (note that this is a bit complex as cow.patch placement of the text generally doesn't come with a background for the full grid area it's place it in.
