What colors can fish not see?

Fish can’t see colors that are invisible to the human eye, such as ultraviolet (UV) and infrared (IR) light. This means that fish can’t see reds, greens, or blues the way humans do.

Some fish may be able to detect changes in color that we can’t see, but for the most part, they rely on their other senses to find food and navigate their surroundings.

Most fish cannot see colors that are red, orange, or yellow. This is because these colors are on the long-wavelength side of the visible light spectrum, and fish typically see best in the blue-green range.

Some fish can see a very small range of colors near the red end of the spectrum, but for the most part, they are colorblind to hues outside of blue and green.

Fish cannot see red or orange. They can see some shades of green and blue.

It’s interesting that fish can’t see the colors that we humans see the best. This is because fish evolved in an environment with different light sources than we have here on land.

For example, in the ocean, there is a lot of blue light due to the water, and less red and orange light since those colors are absorbed by the water. This is why many underwater creatures such as coral and tropical fish have bright blues and greens in their coloring.

Fish can’t see colors that are outside the visible spectrum. This includes ultraviolet (UV) and infrared (IR) light. This means that fish can see colors like red, orange, yellow, green, blue, indigo, and violet.

Fish can’t see certain colors because their eyes have evolved differently than human eyes.

For example, fish cannot see red and orange colors because these colors are on the opposite end of the light spectrum from what fish can see.

This means that fish primarily rely on blue and green colors to find food and navigate their surroundings.

Fish cannot see colors because their eyes lack the cone cells that allow humans and other animals to see colors. Instead, fish see in black and white.

Some fish may be able to see some colors if they are close enough, but for the most part, they rely on their other senses to find food and avoid predators.

Famous fishing tackle brands make braided fishing lines in different colors: blue, green, orange, red and others. So, they believe that fish don’t see these colors underwater.
On the other hand, wobblers come in all kinds of colors and shades to attract fish and for them to see the bait.
From personal experience. Swimming at night with a red flashlight, I noticed that fish are not afraid of red light.
This topic could go on endlessly. There is no exact answer. It is necessary in each situation to make a decision specifically to the fisherman – what color bait, line, string, sinker and plastic balls.
