Wiemann has used the approach to identify pigments in dinosaur eggs.

The pigments — chlorophylls, in green plants — absorb light and transfer the energy to a reaction center, where the production of chemical energy for the cell’s use is initiated.

The pigments needed to absorb light at similar wavelengths to reduce the internal noise.

It brings together oxygen and a pigment called luciferin to create light.

That light is caused by the pigment that gives the corals color.

Although the equipment is the same, a tattoo artist uses ink, and we use pigment.
