  @doc """
  Sets the background color of a cell.

  ## Parameters

  - `spreadsheet` - The spreadsheet struct
  - `sheet_name` - The name of the sheet
  - `cell_address` - The cell address (e.g., "A1", "B5")
  - `color` - The color code (e.g., "#FF0000" for red)

  ## Returns

  - `:ok` on success
  - `{:error, reason}` on failure

  ## Examples

      {:ok, spreadsheet} = UmyaSpreadsheet.read_file("input.xlsx")
