Choice of the colors used, as well as their order, is aimed at an interaction – influencing and changing each other forth and back. | Thus, character and feeling alter from painting to painting without any additional 'handwriting' or, so-called, texture. | Though the underlying symmetrical and quasi-concentric order of squares remains the same in all paintings – in proportion and placement – these same squares group or single themselves, connect and separate in many different ways | In consequence, they move forth and back, in and out, and grow up and down and near and far, as well as enlarged and diminished. All this to proclaim color autonomy as a means of plastic organization. | 6 short quotes from: 'The Origin of Art'
