same color

Quick answer：

The term 'same color' refers to colors that are identical or very similar in hue, saturation, and brightness. It is commonly used in various contexts such as art, design, and color theory to describe colors that harmonize well together. In color theory, the concept of complementary colors is often discussed, where pairs of colors are said to be 'same color' when they are opposite on the color wheel, creating a balance and contrast in a design.
