How to set input field color?

Question

Unity

Good afternoon. I know that the following code is wrong, because I assign different data types, but I think this code sets out the essence of the issue quite clearly.
It is necessary in the course of work to change the color (normalColor, highlightedColor) of the Input Field depending on the change of the player.

if(player_red == true)
        {
            for(int i = 0; i < 4; i++)
            {
                for(int j = 0; j < 4; j++ )
                {
                    var color_field = field[i,j].GetComponent<ColorBlock>();
                    color_field.normalColor = Color.red;
                    field[i,j] = color_field;
                }
            }
        }

Answer 1

normalColor can be changed through the Image component
inputField.image.color = Color.red;

Answer 2

ColorBlock cell = field[i,j].colors;
cell.highlightedColor = PlayerStyle();
cell.pressedColor = PlayerStyle();
cell.selectedColor = PlayerStyle();
field[i,j].colors = cell;
