I don't know what Mr Thomas was talking about.

You can only set the complete visual attribute set for an item. You have to create named visual attributes with the properties you require for foreground and background colours. These have to be created at design time, so you have to know all possible combinations which may be required at that time. You can then assign any of these dynamically to an item at run-time. If you want to set just a specific instance of an item in a repeating block, then use the Display_Item built-in, otherwise use the Set_Item_Property built-in, where the property is VISUAL_ATTRIBUTE.
