Video: Colors are all the way through
Instant Reef® Artificial Coral Reef Inserts have color-fading resistant technology. The colors are mixed into the resin material, all the way through. So technically the colors of the fake corals will not fade.
There is also a layer of painted color giving artificial corals a brand new look, overtime it is normal that this layer of paint may appear a little lighter, actually giving it more of a natural realistic look and feel.
In some cases, sun light, saltwater corrosion, algae covering, fish picking or other factors, may cause the colors to appear this way and is not considered a quality problem.
Instant Reef® Aquarium Decorations use the most advanced anti color-fading technology, making sure colors of our artificial corals are long lasting.
