In the course Color, light and perception with Bengt Ahlin, I created three similar shapes in different shades of paper for my project work. A white shape with a blue tone, a yellow shape with a red tone and a blue shape with a green tone. Then I experimented with changing the color of the shapes and shadows using different colored lamps and filters. Some of the results can be found here below.
