同类色邻近色类似色

Quick answer：

同类色（Complementary Colors）指的是在色轮上相对位置的颜色，如红色和绿色；邻近色（Analogous Colors）是指色轮上相邻的颜色，如红色和红色橙色；类似色（Similar Colors）通常指色彩上较为接近的颜色，但不是相邻或相对。These terms refer to different relationships between colors on the color wheel: complementary colors are those opposite each other on the wheel, like red and green; analogous colors are those next to each other, such as red and red-orange; similar colors are those that are closely related in hue, though not necessarily adjacent or opposite.
