If you want control of how things look, do not use a DataGridView.
A DataGridView is fine for a quick-and-dirty proof-of-concept, but is not suitable for public release.

Solution 1

Why are you looking at the colors of the row instead of including a column in your data that just whether or not the record should be ReadOnly? Then you just check the value of that column in the row and you've got your answer.

You need to select only the row that has been double clicked. Something along these lines.

C#

private void dataGridView2_CellContentDoubleClick(object sender, DataGridViewCellEventArgs e)
 {
   var selectedRow = dataGridView2.Rows[e.RowIndex];
   string msg = selectedRow.DefaultCellStyle.ForeColor == Color.Black ? "Black" : "Red";
   MessageBox.Show(msg);
 }
