Which color scheme consists of tints and shades of one color?

The monochromatic color scheme is characterized by the use of variations of one single hue, created through the addition of white, black, or gray to form tints and shades. Tints are made by adding white to a color, resulting in lighter versions, while shades are created by adding black, producing darker versions of that same color. This approach allows for a harmonious and cohesive look since all colors are derived from a single hue, making the overall design visually cohesive and easy to coordinate.

In contrast, the other color schemes involve multiple colors or combinations of hues. Analogous color schemes use colors that are next to each other on the color wheel, creating a sense of harmony through a range of related colors. Complementary schemes involve colors that are opposite one another on the color wheel, providing high contrast and visual interest. Triadic color schemes consist of three colors that are evenly spaced around the color wheel, offering a vibrant look due to the balance of primary or secondary colors. Thus, the monochromatic scheme distinctly focuses on variations of a single color, making it the correct answer.
