| However, a colorimeter is not appropriate for complex color analysis such as metamerism and colorant strength. |
| The metamerism card is used to check the standard illumination from time to time. |
| The mixed colour was obtained using pigments different from the original ones: metamerism. |
| For instance, many arthropods have lost extensive metamerism but still have remnants in the form of repeated organs. |
| The only other example which we have of this metamerism in the Mollusca is presented by the Chitons. |
| Whether this resemblance indicates a close relationship between monoplacophorans and phyla exhibiting true metamerism is an open question. |
