Do Fish Respond To Color?

Many fish have the ability to see color. Those that do see color have cones, the migrating fish like Shad or Salmon have eye receptors readily adapted which can see green in the ocean and red during spawning.

I saw a show on tv about this once and they proved that goldfish do respond to color.

Fish do respond to colour, to make a fish more calm you might want to use soft colours like a brown or beige like a more natural one, if you want it to be kind of hiding and very edgy then get brighter colours like greens purples reds pinks...ext. It also depends on what colour your fish is, try to match the colour of your fish with the rocks to make it more comfortable so it will blend right in, also plants ans rocks work well.
