The Purkinje effect, named after the Czech physiologist Jan Purkinje (d. 1869), is the tendency for the human eye to perceive light in low illumination toward the blue end of the spectrum. This is why the color of moonlight often looks bluish, especially in rural areas without artificial illumination at night. My Past Present series repurposes traditional vintage quilt tops via cyanotype imagery and stitching, creating contemporary statements.
