Which color harmony involves colors that are adjacent to a chosen color on the color wheel?

Analogous harmony consists of colors that are next to each other on the color wheel, creating a calm and harmonious effect when used in floral arrangements. This color scheme typically includes one dominant color and one or two supporting colors, leading to a cohesive look that is visually pleasing.

The colors in an analogous scheme share a similar hue, enhancing the overall feeling of unity while still allowing for some variation and interest. This technique is often used in floral design to evoke certain moods or themes, making it a popular choice for arrangements.

The other options involve different relationships between colors, such as complementary or split complementary setups, which are based on colors opposite or adjacent in specific configurations, contributing different visual dynamics than those found in analogous harmonies.
