Final answer:
The principle of contrast is used to create disparity between parts of a design for a striking look, with examples including stark contrasts like black and white or subtle ones in monochromatic designs.
Step-by-step explanation:
The design principle that indicates disparity between adjacent parts of a design to give it a striking overall look is contrast. This principle is used to create visual interest and draw attention to certain parts of the design. For example, a stark contrast of black and white can provide a strong visual impact, while monochromatic contrasts offer a more subtle variation, adding depth and unifying the piece. Asymmetry is another way of introducing contrast by creating a visually engaging and dynamic balance through offset compositional elements.
