I think that you need to specify what type of cell the column will contain.

For example:

DataGridViewColumn  newCol = new DataGridViewColumn(); // add a column to the grid
DataGridViewCell cell = new DataGridViewCell(); //Specify which type of cell in this column
newCol.CellTemplate = cell;

newCol.HeaderText = "test2";
newCol.Name = "test2";
newCol.Visible = true;
newCol.Width = 40;

gridColors.Columns.Add(newCol);

DataGridViewCell is abstract, now. Use DataGridViewCell cell = new DataGridViewTextBoxCell(); for example.

Make it simple, in just one line code

this.dataGridView1.Columns.Add(ColumnName, HeaderText);
