How to change the color of rows and text in aggrid on selection

I have a Aggrid and have to change the color of row and text from default blue and black to green and white when we select a row in Aggrid.

I tried making use of this, but the color of links in text does not change to white

It is not related to ag-grid. All you need is to add different CSS rule for links inside a selected row, to override link color (and also, probably, :hover, :active, :focus states).

.ag-row-selected A {
  color: while;
}
