"Round Squares" Red, Black and White Geometric Abstract by C. Mark Brennan

Against a black background, textured like slate, white and gray shapes rise, layered atop one another. In the upper section, a white rectangle casts a shadow that intersects a first square, hollowed at its center, which in turn engages with the lower structure, pierced by a deep, massive black circle. To the right, a white, almost organic curve disrupts the established order. At the bottom, a vivid red line cuts sharply across, traversing the composition horizontally. Christopher Mark Brennan manipulates his choices precisely: black engulfs the space, white illuminates, red shocks, and gray tempers, acting as a bridge between extremes. This gray, scattered here and there, softens the tension, suggesting a transition between absolute black and radiant white—these contrast pit structures against fluidity and stability against dynamism. Geometric abstraction, one of the many experimental terrains of the prolific Californian artist Brennan, reduces reality to pure lines and forms to probe
