How to Choose Lure Colour

What water does to colour

Water filters light unevenly, and that is the whole basis of choosing lure colour sensibly. NOAA states the order plainly: “Blue light penetrates best, green light is second, yellow light is third, followed by orange light and red light.”

The consequence is that a lure does not keep its colour as it sinks. Once the wavelengths that make a colour visible are gone, the object cannot reflect them. NOAA describes exactly this effect in deep-sea fish: at depth a red fish “appears blackish because there is no red light to reflect at that depth, and the fish absorbs all other wavelengths of color.”

Those figures come from the open ocean, where NOAA notes red light is gone by around 100 metres. Most fishing happens far shallower, and inland water is far less clear, so the filtering happens much faster than in blue ocean water. The direction of the effect is what transfers: warm colours go first, and they go first fastest where the water is stained.

Fish can see colour — but not necessarily yours

Fish are capable of true colour vision, so colour is not purely an angler’s superstition. The mechanism is real. In a controlled study of a Lake Malawi cichlid, “most fish were significantly more likely to choose the trained over the distracter stimuli, irrespective of brightness,” which shows genuine colour discrimination rather than a response to how light or dark something looked.

Fish that can discriminate colour can, in principle, respond to it, which is why the question is worth taking seriously rather than dismissing.

What it does not establish is which colours matter to the species you fish. Visual systems differ enormously between fish, tuned to the light of the habitats they evolved in. A cichlid in clear tropical rock habitat is not a stand-in for a catfish in a stained river.

What we could not verify

We found no accessible, published research demonstrating that specific lure colours reliably produce more fish for anglers under real conditions. Colour charts and rules — chartreuse for stained water, natural for clear — are common, consistent enough to be useful shorthand, and largely untested in public research.

There is a plausible reason such research is scarce. Isolating colour from everything else in fishing is hard: retrieve speed, depth, action, light, water clarity and angler confidence all move at once. Studies that have looked at angling outcomes have tended to examine gear configuration or technique rather than colour.

So this guide gives you the physics, which is solid, and stops short of promising results, which is not.

A practical way to choose

The useful question is how visible your lure is in this particular water, not which colour the fish prefer today. Start with visibility, not colour. Ask how far a fish can see in this water, and what will stand out against the background it is being seen against. That question has an answer you can observe; “what colour do they want today” mostly does not.

Clear water, good light. Subtle, natural finishes are visible without looking wrong, and fish get a long look at the lure. This is where translucent and baitfish-pattern finishes make sense.

Stained or muddy water. Contrast beats subtlety. Dark, solid colours give a strong silhouette; bright, high-contrast patterns are easier to track. Both work for the same underlying reason — they are easier to separate from the background.

Deep water or low light. Remember that warm colours are already gone. A dark lure viewed from below against a lighter surface gives the clearest outline, which is why black and dark profiles have such a following for night fishing.

Overcast versus bright. Less light reaching the water compresses the same effect into shallower depth, so treat a dull day slightly more like deeper water.

Let other senses do some work

When visibility is genuinely poor, colour has limited room to matter. Vibration from a blade or a wide-wobbling body, a rattle, or a bulkier profile pushing more water gives fish something to find that does not depend on light at all.

The same logic applies to speed. A lure moving too fast in murky water can pass a fish before it is detected, regardless of how visible the colour would be under better conditions.

Water clarity and light also change with conditions on the day — wind that stirs a shallow bank changes visibility within an hour. Our guide to how wind affects fishing covers that mechanism.

Limitations and context

The NOAA figures describe open ocean water. Fresh water, especially stained or algae-rich water, absorbs and scatters light differently and much faster, so treat depths in this guide as direction rather than measurement.

Confidence is also a real factor and worth admitting. An angler who trusts a colour fishes it more carefully, longer and in better places, and that alone can change results. If a colour makes you fish better, that is a legitimate reason to tie it on — just not evidence that the fish agree.
