You can avoid the background painting code by using the e.PaintBackground call. Also you have to draw the strings only when the ContentForeGround is being painted. Use the e.PaintParts to identify the painting operation. See my sample code for its usage. It needs tweaking but you'll get an idea.

Sample Code:

void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)
{
    if (e.RowIndex != -1 && e.Value != null && e.Value.ToString().Length > 5 && e.ColumnIndex == InterestedColumnIndex)
    {
        if (!e.Handled)
        {
            e.Handled = true;
            e.PaintBackground(e.CellBounds, dataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected);
        }
        if ((e.PaintParts & DataGridViewPaintParts.ContentForeground) != DataGridViewPaintParts.None)
        {
            string text = e.Value.ToString();
            string textPart1 = text.Substring(0, text.Length - 5);
            string textPart2 = text.Substring(text.Length - 5, 5);
            Size fullsize = TextRenderer.MeasureText(text,e.CellStyle.Font);
            Size size1 = TextRenderer.MeasureText(textPart1, e.CellStyle.Font);
            Size size2 = TextRenderer.MeasureText(textPart2, e.CellStyle.Font);
            Rectangle rect1 = new Rectangle(e.CellBounds.Location, e.CellBounds.Size);
            using (Brush cellForeBrush = new SolidBrush(e.CellStyle.ForeColor))
            {
                e.Graphics.DrawString(textPart1, e.CellStyle.Font, cellForeBrush, rect1);
            }
            rect1.X += (fullsize.Width - size2.Width);
            rect1.Width = e.CellBounds.Width;                    
            e.Graphics.DrawString(textPart2, e.CellStyle.Font, Brushes.Crimson, rect1);
        }
    }
}
