Natural and attractor colours

The split into “natural” and “acid” colours isn’t two tastes but two different calculations, and they’re applied in different conditions.

Natural: matching the forage

A silver flank, an olive back, a brown belly — the colours of the forage fish, crayfish and larvae that actually live in that water. The silver shine of scales itself comes from guanine crystals in the skin — which is why “silver” in lures is the most natural colour there is for our silverfish. Natural tones work in clear water and in daylight, that is, wherever a fish has time to look closely.

Attractor colours: deliberate mismatch

Acid yellow, orange, toxic lime-green don’t occur in nature. The calculation here is the opposite: the lure isn’t meant to be mistaken for forage — it’s meant to be spotted from the maximum possible distance and hit on reflex, without a second look.

Where they work

In murk, at depth, in dim light, in current — anywhere there’s no time to look closely. There it’s visibility that wins over resemblance, and the very colour that scares a fish off in clear water becomes the only one visible at all. Current adds seconds to the equation too: the fish decides on the move.

A clear body is a third case

Soft plastic also has clear colours that metal simply can’t have: the body lets light through and, backlit, reads as a silhouette with blurred edges. That’s not a “weak natural” — it’s a state of its own, something between the lure and its shadow.

Glitter in the body

Tiny flakes mixed into the soft plastic body don’t work as colour but as micro-mirrors: they add an intermittent flash without changing the body’s shade. So the same model in clear and “with glitter” versions differs in flash, not in colour.

Two-tone lures

A dark back and a bright belly is an attempt to run both logics at once: from above the lure looks natural, from below it’s conspicuous. Metal is finished the same way: spoons often have one side matte and the other mirrored, and whichever faces the fish at that moment is the one that works.

The red detail

Red hooks, a red dot at the gills, a red thread on the knot — a separate trick usually explained as mimicking blood or gills. Red is the first colour to disappear with depth, so this trick only works at shallow depth in any case.

What we don’t write here

We don’t call either logic the right one. Both have existed for decades and both sell lures, and no one has managed to run a clean trial between them on live water.
