Have you ever painted a house interior? If you ever did, you would know the blue tape (and so does every color painter's tape as long as it is paper) pulls the paint some. Also, the painter's tape simply is not for thin pigments, it is for thick liquids containing no solvents like those used in certain lacquers and such. They will soak the tape as it is paper and it will start pulling the pigment.
