The best combination of two colors

Quick answer：

The best combination of two colors can be influenced by various factors such as the context in which the colors are used, the cultural connotations, and the psychological effects. In design, a common approach is to use complementary colors, which are opposite each other on the color wheel, to create a dynamic and visually appealing contrast. For example, blue and orange or red and green. However, the most suitable combination also depends on personal preference and the specific purpose of the color scheme.
