In learning about positive and negative space, one thing that I was introduced to in reading this article was using color to create a blending effect between the two. Previously I thought of positive and negative space as two distinct (and opposite) things, but this article showed me that positive and negative space can be subjective, and can blend together in different ways.
Reading this article helps me think of different ways to structure my Gestalt designs and how to manipulate colors and positioning to bring into focus various elements.
