Green, red, blue color design matching

Quick answer：

Green, red, and blue are the primary colors in the RGB color model, widely used in design and art. A well-balanced combination of these colors can create a visually appealing and harmonious design. For example, complementary colors like green and red or blue and orange can be used to create contrast, while analogous colors like red and orange, or blue and green, can be used to create a sense of unity. The choice of color combinations depends on the desired emotional response and the context of the design.
