Design of poster tricolor color scheme

Quick answer：

The design of a poster with a tricolor color scheme involves selecting three colors that complement each other visually. These colors should be chosen based on their harmony and contrast, considering factors such as the message of the poster and the target audience. Techniques include color theory, where primary colors (red, blue, yellow) are mixed to create secondary colors (green, orange, purple), or by using complementary colors (colors opposite each other on the color wheel) to create a striking effect. The goal is to create a visually appealing and cohesive design that effectively communicates the intended message.
