Hi everyone, I am trying to change the colour of the bottom of my balcony/deck. When you create a deck and then add a fence there’s a white strip on the bottom of the fence and I don’t know how to change the colour pls help )

@aesthetic_petals  Click the Create a Style tool on the user interface; it's the one that looks like a paint palette and is in the same area as the hand and sledgehammer tools.  With the Create a Style tool selected, click on the bottom of the deck, and choose a different color and/or pattern.
