Dear fany Sure. Actually the goal of measuring colors precisely (as explained in this video) is to be able to compare colors. For example, there are many colors that their RGB values are similar but the colors are different. So, using the color measurement that explained in this video and obtaining the precise color values (XYZ values), we can compare colors of objects correctly.
Can we get the color values of 2 object to compare them?
