Final answer:
The design principle of contrast makes elements in a design look very different, creating a focal point and drawing the viewer's interest through the effective organization of elements and visual effects.
Step-by-step explanation:
When used well, the design principle of contrast makes elements in a design look very different. Contrast instills vitality and interest into a piece of art or design, creating a strong center of interest that draws viewers in and keeps their attention. This can be achieved using stark differences like black and white or through more subtle methods, such as varying shades within a color family to provide unity and variety. In the context of graphic design, contrast can also dictate how different elements on a layout interact and stand out.
Using contrast effectively is crucial for good composition, as it helps in visually organizing the elements of design and upholding a high standard in artwork, ensuring that unity prevails over chaos, and that variety maintains interest over boredom. It is a principle that can be reliably applied to produce visual effects that enhance the visual communication of the artwork or design.
