What type of color palette uses two colors that are opposite each other on the color wheel?

The correct choice refers to a complementary color palette, which specifically consists of two colors that are positioned directly opposite each other on the color wheel. This pairing creates a strong visual contrast, making each color appear more vibrant when placed next to its complement.

For example, when you consider the color wheel, the complementary color of red is green. When used together, these colors can create dynamic and striking visuals, commonly used in design and art to attract attention or create a sense of balance.

In contrast, analogous color palettes include colors that are next to each other on the color wheel, typically creating a more harmonious and serene look. A monochromatic palette is derived from one single hue that includes its various shades and tints, focusing on the same color but with different intensities or saturation. The triadic color scheme consists of three colors that are evenly spaced around the color wheel, which also provides a vibrant and balanced visual impact but does not emphasize the contrast as much as complementary colors do.
