In the doc for 'Spreadsheet::WriteExcel' there this example for conditional color based on positive or negative percent value:

$f_change->set_num_format('[Green]0.0%;[Red]-0.0%;0.0%');

I would like to do something slightly different: Green if over 80%, orange if over 40%, otherwise red. However I cannot understand the syntax of the format string

Everything I have tried results in excel complaining about the format and asking to recover the document :-(

Any ideas? Thanks!
