Many people might answer "with the human eye", but this is actually not comprehensive. The human eye cannot accurately distinguish the colors of similar objects. Furthermore, everyone's perception of color varies. Therefore, people have developed color measurement tools based on the CIE color system. 

Currently, there are two main types of commonly used colorimeters, as follows: 

Colorimeter - It is an ideal choice for quality control (QC) on production lines, used to detect color differences. 

Spectrophotometer - It is suitable for the development of color characteristics and color analysis in laboratories.
