同类色搭配 and analogous color scheme

Quick answer：

Analogous color scheme refers to a color scheme that uses colors that are next to each other on the color wheel. This technique is often used in design to create a harmonious and cohesive look.同类色搭配 involves pairing colors that are very similar in hue, often with different shades or tones. This creates a more subdued and less contrasting look compared to complementary color schemes.
