Background color of Form in Pavlovia

Hi all,

I am planning to survey using Form component using PsychoPy 2021.3. When compiling the test in local JS debug, the color of background is black. I want to change background and item color but I can’t find the color option. I tried to change style option but the problem has not been solved. How can I control the color option in form? Any advice would be appreciated.

Thanks!
