| However, a colorimeter is not appropriate for complex color analysis such as metamerism and colorant strength. |
| Most provocative of all the Ediacaran forms are those exhibiting real or apparent metamerism. |
| Whether this resemblance indicates a close relationship between monoplacophorans and phyla exhibiting true metamerism is an open question. |
| Tagmosis can ultimately lead to the outright fusion of neighbouring segments and the loss of apparent metamerism, as seen for the arthropod head. |
| For instance, many arthropods have lost extensive metamerism but still have remnants in the form of repeated organs. |
| It's an essential tool for visual colour assessment, comparison of colour variations and the detection of metamerism. |
