Using colors

The list of colors that can be defined by name is: 'black', 'white', 'red', 'green', 'blue', 'yellow', 'magenta' and 'cyan'. If you want to know how the other indexed colors look like, you can see it here. Beware that the color indexes are displaced by 1 with respect to those used by Spreadsheet_Excel_Writer.

If non of the predifined colors seems to be the color you are looking for, don't despair. You can use the setCustomColor() method to define a new color by its RGB components.
