Changing the background color in builder to white instead of gray

Hi

I am trying to change the background color from gray to white. How can I do this? Sorry this is a really simple task but i couldn’t find anything that would enable me to do this.

thanks

OS (e.g. Win10): mac sierra
PsychoPy version (e.g. 1.84.x): 20202.2.3
Standard Standalone? (y/n) If not then what?: built scratch

Go to the experiment settings and there is a background colour setting on the display/screen tab.
