The reliefs lasted about a year after which I returned to my previous work but now the allovers became "one" color as opposed to the previous multicolored ones. In the mid-nineties a Rothko at MoMA started me thinking about the effect I had noticed and liked when I placed one of my colored fields next to another. It was about five years before I started making use of this concept. It first expressed itself as a form on a field, similar to work in the mid eighties.
