Contrast is one of the main principles of art and refers to arranging opposite elements to create visual interest. Contrast can be created through differences in light and dark colors, rough and smooth textures, large and small shapes, or thick and thin lines. Several artworks are discussed as examples of using contrast between organic and geometric shapes, colors and textures in nature photographs, complimentary colors and sizes in a still life, curved and straight lines in a woodcut print, and focused versus blurred space in a photography.
