People with negative taste make things by trying something very simple and then stripping away pieces until it looks good. They can detect goodness, but not create it, so they’re limited to designs with very few variables, because then they can go thru all the options and pick out the ones that look OK. People with positive taste, on the other hand, can make things that genuinely look good. This gives them a lot more freedom in their designs (they can use colors other than white!).
