Blue is kind of a funny color in the world of aquascaping. If somebody mentions the words, “ocean,” “water,” or “river,” what’s the first color that comes to mind? Blue, of course. In aquascaping, though, blue is somewhat underrepresented. You might think that it would be the dominant color in every single aquarium, but that isn’t really the case. Some aquariums don’t have any blue at all, while some aquascapers go out of their way to highlight colors other than blue. Luckily, there are still plenty of options for aquascapers who want to create a cool blue aquarium.
As the color of water, blue is a very relaxing and soothing color. It is considered the most calming of all of the colors. Blue also gives off a feeling of cleanliness or purity. Think of a clear blue sky or the ocean on a sunny day — it’s blue as far as the eye can see. All-blue rooms and blue aquascapes mimic that feeling.
Creating a Blue Aquascape
When it comes to the color blue, deciding whether you want a freshwater or saltwater aquarium is a major decision — even more so than with any of the other colors. The reason why it’s such a big deal is because salt water is naturally blue, while fresh water is completely colorless. You need blue fish if you want to have a blue freshwater aquarium, whereas saltwater aquariums will be blue by default.
That being said, there are still a number of blue fish that can help make your saltwater aquarium even more blue-tiful. The regal tang (aka blue tang) will add vivid neon blue to your aquascape. There’s also the psychedelic mandarin fish, the blue koran angelfish, and the powder blue surgeonfish. You might want to be careful if you’re designing a blue saltwater aquascape, though. If you have blue water and blue fish, then everything might begin to blend together. Break things up by choosing multi-colored fish, such as the mandarin fish.
Most of the principles that apply to green rooms also apply to blue rooms. Blue is a great color for bedrooms and other relaxation rooms. Beware of dark shades of blue, however. They can make the room feel chilly if there isn’t a lot of natural sunlight and particularly dark shades of blue can make people feel depressed.
Blue has been known to suppress appetite, so it’s not a great choice for dining rooms and kitchens. Avoid using blue in rooms that are supposed to provoke a lot of excitement and small talk. You don’t have to worry too much about aquariums, though. Blue aquariums can fit in just about anywhere as long as you’re careful not to overuse the blue color scheme.
