I love the wisteria in Cottage Living but really wanted a white version with paler green leaves. As well as recolouring the regular Build/Buy Catalogue items, I also recoloured the debug wisteria and changed the tuning so it shows up as regular Build/Buy wisteria (thanks to this tutorial over at Sims 4 Studio). There are 5 regular items and 6 debug items.
You can find the items in the Build Catalogue under Wall Sculptures and the Buy Catalogue under Wall Decorations. The items pulled from debug do not have the Maxis description.
