"Show me the PWM signal"
"like this"

I am asking you to show me how you are generating the signal as many circuits can be changed to produce an inverted signal and simply passing them through a transistor will invert the signal .

Not much anyone can do beyond this... Bobk mentioned it further up, and Colin is trying to give you more specific help based on the actual circuit you have. (Which you have not shared)

... Generating the signal 'for' or 'from' the Arduino?

You know you could just program the arduino to output the PWM signal in the fashion you want...

If the signal is generated by software, simply reverse the instructions that turn it on vs the ones that turn it off.

Logic at it's finest ;)
Stand by for code example requests.

Show us your program, and we can take another look.

Oooh! It's not a program if it's Arduino, it's a sketch! Lemme see if the cookbook has a recipe for PWM inversion...
