Corals mainly show colors in 2 different ways. One way is the way that they fluoresce under UV light. These colors tend to be super bright and glow in a almost otherworldly way, they show up best under actinic or blue-heavy lighting. They can shift in brightness and hue depending on the color light they are under. So some corals that may typically show brown under normal white light will fluoresce bright blue/green/or orange under UV light.
Another way that corals will show is with true pigments in their flesh. Chromoproteins and carotenoids will absorb certain wavelengths of light and reflect other colors under white or ambient light. This means that no matter what color light the coral is under it will still keep its original color. That being said do you have a preference for one or the other when you stock your reef tanks?
