Neighboring Color Poster Design

Quick answer：

Neighboring color poster design refers to the use of colors that are next to each other on the color wheel in poster design. This approach can create a harmonious and visually appealing composition. It involves selecting colors that complement each other, typically from the same color family or with a slight difference in hue, saturation, or brightness. Neighboring colors are often used to evoke certain emotions or convey a specific theme. This technique is widely applied in graphic design to enhance the overall aesthetic of the poster.
