What colors are considered to contrast or complement each other?

Colors that are opposite from each other on the color wheel are considered to contrast or complement each other. This pairing creates a dynamic visual relationship because the high contrast between these colors tends to make each hue appear more vibrant.

When two complementary colors are placed next to one another, they enhance each other's intensity. For example, the combination of blue and orange or red and green is striking because these colors have a high level of contrast that can capture attention and create visual interest.

The other options, while related to color theory, do not represent complementary relationships. Adjacent colors on the wheel typically share a hue and create a harmonious feel rather than a contrasting one. Colors that are similar in hue blend well together and are often used in designs to create a cohesive look but lack the contrasting quality. Neutral tones, such as grays and browns, do not possess the vibrancy or visual conflict needed to serve as complements to other colors on the wheel.
