Best settings for background pink noise

I am trying to create a pink noise background in a RSVP experiment as a way to mitigate flashes artifacts of a gabor patch. Since I am totally beginning with it I am not sure what would be the best, most common, settings to start with. I have the following for now (see screenshots). Any recommendations? Cheers

OS (e.g. Win10): Win10
PsychoPy version (e.g. 1.84.x): PsychoPy v2021.2.3
Standard Standalone? (y/n) If not then what?:y
What are you trying to achieve?: pink noise with the noise component in the builder

What did you try to make it work?: see screen shot

What specifically went wrong when you tried that?: jut trying to figure best settings
