Change the background color on just one routine?


My study is set on a white background, but for one routine I want to change it to a gray background. Essentially, the routine lasts 5 seconds, and after 3 seconds I want the background to go grey. Is this possible to do online? I saw some other topics about adding a polygon, and I tried that but I am not sure how the polygon would work - if it’s transparent, it doesn’t show anything, but if it’s opaque it covers the image I want to present in the middle.

Hi, so if you have a polygon the size of your screen (2,1) usually covers the whole screen and ensure this component is the on top of your other components within the routine, this will place it at the back of everything as it is drawn first - so similar to sending something to the back in powerpoint.
