Why is the electronic Pantone color card so different from the standard color card?

The color seen by each computer will be slightly different, because the monitor is color-cast, and the eyes may not see the exact color. In addition, although the color number and number you provided are the same, the suffix is different, which proves that the material is different. C is a bright color and u is a matte color, which will definitely be different. It is suggested that the color of the physical color card shall prevail!
