First, you need to have a 12mmx22mm label that can print text, of course, you can also handwrite, the concave part of the model can just put a 12MM x 22MM label, you can also cut it into the same size and paste it in, because the size of this color card Some Chinese characters or too many characters will cause it to be very blurry, or cannot print Chinese, so I re-modified this color card sample.

This color card uses Swatch Display Board by Bambu Lab from Bambu Lab - MakerWorld to store and display the swatches.
