According to industry articles, most fish are capable of seeing most of the primary colors in the spectrum. Unfortunately, we don't know what the fish associate with those colors when they see them. Do they think it's food? Or maybe an enemy? We're not sure, but we do know that color can make the difference between a monster catch and a embarrassing day on the lake.

Coloring a Soft Plastic
Soft plastic lures can be colored in a variety of ways, the most common of which involves mixing liquid dye into the plastic prior to molding. Unfortunately, this technique limits the number of multicolor lures that can be produced in a given time frame because it requires preparing multiple batches of colored plastic and sequentially layering them within the mold. To avoid this delay, many commercial soft plastic manufacturers have started "printing" lures. This process involves producing a single color lure (usually clear) and then applying a finishing coat of color to produce a multicolored pattern. After the pattern coat is applied, the lure is given a final thin clear coat of plastic to seal it.

Different Fish See Different Colors
In order to see color, a fish needs to have at least two cone cell types in its eyes. Bottom-dwelling fish (i.e. catfish) have only one type of cone cell so they see everything in shades of gray - they can determine an object's brightness, but not its color. Many shallow water surface-fish (i.e. trout, minnows, carp) have four cone cell types, allowing them to see all colors, including the hidden ones in the ultraviolet spectrum. Other fish such as the bluegill and the bass have two cone cell types, limiting their color distinctions to black, browns, greens and reds (and possibly yellows for the bass). Although most of these fish can discriminate between very fine shades of the colors they can see, this ability has no effect on what they select for food - a fish will be equally excited by a red lure and a tomato lure.

Unfortunately, there is no chart explaining the color viewing capabilities for each species of fish. With this is mind, it is best to make color selections based on color contrast rather than actual colors. For instance, pick a lure with two colors that would appear differently, regardless of their actual color. Here is an example of how a some fish might see a blue and red lure - notice the color contrast exists in all three views:




Color Filtration in Water
Water filters light. And since all color is actually colored light, water will filter colors. Certain colors cannot be seen below certain depths because light is broken apart when it hits the water and certain wavelengths (colors) are filtered out. The severity of this filter depends on the clarity of the water, wind conditions, time of day and lure depth; dirty water, high winds, deep water, and evening hours mean fewer colors. To understand these effects, we must first understand the relationship between light and water.

The colors of the spectrum (the colors of light) are Red, Orange, Yellow, Green, Blue, Indigo, and Violet. A mixture of all of these colors produces white. If an angler were to stand in the center of a very deep lake and shine a bright light into it, the colors within the light beam would gradually disappear as it traveled toward the bottom. At 10 feet, red is almost gone, orange is disappearing, and yellow is starting to fade away. At 35 feet, orange is gone, and yellow is quickly disappearing. At 75 feet, yellow looks greenish-blue and the only visible colors are blue, indigo and violet. As we pass 150 feet, blue and indigo are hard to see and violet is disappearing. At a few hundred feet, ultraviolet is the only color left, and it is not visible to the human eye anyway.



Neon colors, however, do not disappear when the spectrum colors do. This is because they "fluoresce", meaning that they glow when hit by ultraviolet light. We have heard reports of brightly visible fluorescent pink and yellow colors at depths of 125 feet and deeper!

Keep in mind, however, that these water color filtration rates assume that the water is crystal clear. Pollutants, sediment, and wind can drastically affect these numbers by rearranging the filtration order and decreasing the overall depths of all colors. Under these circumstances, red-orange seems to be the most visible, assuming that your lure depth is not greater than 20 feet. That said, here are some tips from anglers on how to pick lure color:

Super Clear: White or clear. Use glitter for color. All colors are visible to 10 feet.
Clear Water: Blue is most visible. White is visible. All colors are slightly visible to 10 feet.
Green Water: Green is most visible.
Stained Water: Orange, green, and chartreuse are most visible. Red is slightly visible.
Muddy Water: Red is most visible.

Here are some additional suggestions to help with low light (first light until sunup), medium light (sunup until the sun reaches 20 degrees to the horizon), and high light (from 20 degrees to the opposite horizon) conditions:

Low Light: Blue, purple or black work best. Use with silver flash.
Medium Light: Red and orange work best.
High Light: Brown or gray work best. Use with fluorescent accents.

NOTE: When the light level falls below 0.1 foot candle (clear night, no moon), all colors become just shades of gray and cannot be seen by the fish.
