    I've heard that fish can't see red under water. If that's true why do lures have red gills painted on them? I also heard that the red on the lures make fish think that it's a wounded bait fish.

    There's red fishing line, red salmon eggs, red hooks, red lures, red power bait, etc.

    What do you think? Can fish see red or not? :confused:

    I have heard that fish can see the color red in 12ft of water. The light does not reflect red under depths greater than 12ft. I have no idea how they can tell how fish see, but I guess it is the same way they tell how bees can see?

    Here is a good explanation I found:

    "Most fish can see in color. As in people, the retina of a fish's eye contains two types of cells, rods and cones. Cones are used for day vision and are the cells used to see colors. Rods are used for night vision and cannot distinguish colors, although they can judge light intensity. The eyes of most freshwater fish contain both rods and cones, though day feeders tend to have more cones, and night feeders more rods.

    In theory, then, day feeders like bass, trout, and salmon are more sensitive to color than night feeders like walleyes. Studies have shown that rainbow trout and Pacific salmon have color vision similar to that of humans. They can distinguish complementary colors and up to 24 spectral hues. Other studies have shown that brown trout are capable of sharply focusing on near and far objects at the same time and that they can clearly see different colors at different distances.

    But light behaves differently in water than it does in air. The various colors of light travel at different wavelengths. The longest wavelengths are the reds, followed by oranges, yellows, greens, blues, indigos, and violets. When light travels through water, some of its energy is absorped, and the longest wavelengths are the ones absorbed first. Thus, the warmer colors fade out and gradually appear black as light penetrates the water column. Red light is almost completely absorbed within the first 15-20 feet. Orange penetrates to 30-40 feet, and yellow to 60-70 feet, while green and blue remain visible for as deep as the light penetrates."

    Great post Jerry, I didn't know that. The color selector must work like the eye to tell you about lure color?

    Lures with red on them is supposed to represent blood emitting for ma wounded fish similar to putting a red hook on a rattle trap, supposed impersinate a wounded fish bleeding in the water. For preadatory fish like Bass they are supposed to see the "fake blood" think it is an easy target and attack.
