△ Eab spherical color difference

Abstract: △Eab色差公式是全球广泛使用的色差测量工具，它通过计算两个颜色在颜色空间中的距离来量化色差。该公式用一个数值表示总色差，△Eab值越小，两种颜色越接近，视觉上差别越小；△Eab值越大，颜色差异越显著，视觉上差别越明显。

The △Eab color difference formula is currently the most widely used color difference formula in the world, and its essence is the distance between two colors in the color space.

The △Eab color difference formula expresses the total color difference with a numerical value.

The smaller the △Eab value, the smaller the color difference between the two colors, and the closer the two colors are visually;

The larger the △Eab value, the greater the color difference between the two colors, and the more obvious the visual difference between the two colors.
