Colors appear differently in ambient light, in clear tissue, in pigmented tissue, and when fluoresced. Tags of different colors can generally be distinguished in ambient light in clear tissue, but those same colors may be confused if the marks are poor or are placed under pigmented tissue. To maximize tag identification: - Choose distinct colors for tagging (see Selecting VIE Colors).
- Tag in clear tissue whenever possible.
- Train your samplers – let them practice with the tag colors they will encounter before they start collecting data.
- Use the VIE Color Standard to correctly identify colors.
- Use the VI Light to fluoresce poor or obscure marks.
Using the VIE Color Standard | NMT’s VIE Color Standard presents the ten VIE colors on a clear card. This allows the sampler to place the color sample directly beside a tag for comparison, either under or over the tagged tissue. Customized color standards can be made at the time of tagging by dispensing some tags onto clear stiff plastic and then covering them with clear packing tape after the marks have cured. Labeling the colors is helpful. |
Using the VI Light
NMT's VI Light | Test the VI Light with the VIE Color Standard to ensure that the tags are adequately fluoresced. Shine the light directly on the area where the tag is thought to be. Do not use an amber filter with the VI Light. If you are working in direct sunlight, you will need to fluoresce the tags in the shade – even the shade of your body is probably enough. Very faint tags are best seen when fluoresced in darkness. | | | |  | CAUTION! |
