Food Coloring for that Deep Ocean effect?

if you feel such a great need to make the tank looked colored to you why not just cover the outside glass with see through colored plastic. less messy and probbly wouldn't mess with the fish as bad as foodcolored water.
 
Back to the humming bird feeder. I watched these wasps fly out of my yard to who knows where carrrying this liquid with them. I think there are some wasps and bees in my yard that are extinct in some places.
My house is 120 years old and most of the former owners didn't take care of it. there are so many bee hives or different varieties I can't believe it. some day I might have to to the fumigating thing but I don't want to kill my mantises.
 
Conductivity??? What ions in food coloring are going to affect this???
How can you be absolutely sure the fish like looking through brown water (tannins)???
Tannins change the water color and chemistry but they're good? If food coloring changes the color and chemistry they're bad??:confused:

BK offers a good alternative, but if you go back to the original post, I stated I have no intention of adding food coloring to my tank. I was just curious.:p

p.s.- yes I'm aware of the "benefits" of tannins.

I think this thread can be seen mostly as a brainstorm of ideas reguarding the food coloring issue. We are just throwing in our 2 cents on the topic.

Personally I have always preferred the natural approach to aquarium keeping and that is always highly reflected in my statements.
 
Just a thought. Are fish colorblind? If they are then changing the color of the water wouldn't really affect them in a psychological sense (I'm not currently talking about the chemical sense). But maybe if they're color blind if we change the water color, then they see in color!:D How do we know that they don't want to swim in different colored water. I know I have always wanted to swim in a pool with red water, how cool would that be?

Also, talking about psychadelic confusion reminded me of my science teacher doing an experiment where he adds a few different liquids together and mixes and every 5 seconds the water changes from blue to white to red to blue. Wouldn't that give the fish some confusion.:confused: It would also be cool if you could add harmless dies that would stay in layers, so you could have the top half of the tank blue and the bottom green. It would be like having a two story tank.:p
