Solution 3

C#

string tempStr = String.Empty;
private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e)
{
        if ((dataGridView1.Rows[e.RowIndex].Cells[1].Text) != tempStr)
        {
             dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Blue;
             tempStr = dataGridView1.Rows[e.RowIndex].Cells[1].Text;
        }
        else
        {
            dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;
        }
}

I did not test it, there may be syntax errors.
