How do you set a column to a specific color without losing the cell selection and cell edit coloring?

I am using style to set each column to its own unique color like this.

.aw-column-1 {background: #FFCC99;}
.aw-column-2 {background: #CCFFCC;}

The problem is that when I do this the selected cell no longer shows up in blue and cells in edit mode don’t turn to white. The cells just stay the same background color set for the column.

Thanks in advance for any help

I have to ask the question in order to figure it myself

.aw-cells-selected { color: white;background: blue  ;} 
.aw-edit-cell { color: black;background: white ;}
