How is a tetrad color scheme defined?

A tetrad color scheme is defined as a selection of four colors that are evenly spaced around the color wheel. This approach allows for a balanced and harmonious palette because the colors are designed to work well together while providing enough variety to create visual interest.

In a tetrad, the colors include two pairs of complementary colors, which are opposite each other on the color wheel. This spacing enables the creation of dynamic designs that can incorporate contrasting elements, enhancing the overall aesthetic. The balance achieved in this scheme makes it ideal for compositions in floral arrangements, graphic design, and other artistic endeavors where color plays a crucial role.

The other choices describe different concepts in color theory. Blending colors, as mentioned in the first option, pertains to a different technique where colors intermingle rather than maintaining distinct relationships. Similarly, the third option discusses tints and shades, which are variations of a single color and do not relate to the spacing of colors in a scheme. Finally, the fourth option refers to a monochromatic scheme, where variations of one hue are used, again contrasting with the idea of a tetrad where multiple distinct colors are utilized.
