Zebrafish are known to detect color and brightness with the pineal gland, which is part of the brain. How they do so is now being elucidated. We see color because photoreceptor cones in our eyes ...

Additionally, once the materials change color, that color change is irreversible, another first. The current standard for chemical threat detection using color change is M8 paper.
