Word 2013, change background color of table cells

In Word 2013, I have a table of many rows and columns

I elect 2 fields (2 middle columns in 2 different rows)

I want to change the background color, but do not see an option to do so

I see Table - Design, and Table Layout, but do not see a way to change the background color of the two cells I selected

What path do I take to get there ?

Thanks
