Coral Coloration: Understanding the Science Behind Vibrant Reefs

Few things capture the magic of a reef tank like the vivid blues, greens, and pinks of thriving corals. But have you ever wondered why corals change color—or sometimes lose it altogether? Coral coloration is more than just eye candy—it’s a direct reflection of your tank’s health, lighting, and nutrient balance.

This article unpacks the science behind coral pigmentation and offers practical guidance for hobbyists aiming to achieve vibrant, lasting color in their reef aquariums. From lighting spectrum and intensity to water chemistry and nutrient control, you’ll learn the key factors that influence coral color and how to fine-tune them for stunning results.

What you’ll discover:

• The role of zooxanthellae and pigments in coral coloration
• How lighting spectrum and PAR impact coral vibrancy
• The effect of nutrients and trace elements on coral health and color
• Tips and strategies to restore faded or browned corals

Whether you’re troubleshooting dull corals or chasing that show-stopping glow, this guide will help you understand and unlock the full potential of coral coloration in your reef tank.

20 years into LEDs and there is still no way around this... you still need full daylight to render the best color in most true coral. Then, you can blue it up all that you want to illuminate.

Horrible false equivalency, but think of daylight as exercise, diet and skin & body care. Blue light as spanx, makeup, hair extensions. Both are great together, but without the daylight, the tricks don't last for long or work as well.

Even a few hours of daylight can do wonders. Mix in some IR and UV for best results. I know that the article was basic, but 350-850nm are great for coral color, and growth. Hubris of man to think that only 400-700nm matters since this is what our eyes can see.

The people who have used multiple bulb T5s have seen tremendous benefit from even a single 6500k bulb.
