Kate Beck is a Maine-based artist whose primary palette includes black, white, and grey. Her Form Surface series, which are line paintings and drawings that are created by using things like graphite and poured oil and enamel on aluminum, paper, and linen, are studies in tonal gradation. The minimal works are impressive to say the least.
I believe white to be the most inherently beautiful color as it carries with it the potential to simultaneously expose and negate space.
I believe black to be the most innately powerful color as it is defined by the presence of light as well as by the absence of light.
