Quick answer：

Adjacent color plane composition refers to the arrangement of colors on a two-dimensional plane that are next to each other on the color wheel. This concept is often used in art and design to create harmonious and visually appealing compositions. The adjacent colors are those that are closest to each other on the color wheel, such as blue and blue-green or red and orange. This technique is particularly useful in graphic design, photography, and painting.
