Valid color patterns of spinning lure blades

Design of signalling color patterns in fast-moving objects, including blades of spinning lures, must be grounded upon the following 4 basic rules:

1) stimuli must be bilaterally symmetric

2) color stimuli must be located closer to the center of rotation

3) red colors are rather than blue ones

4) stimuli must be simple

For more information, see On the coloration of fast-moving signalling stimili in the nature

In the water, blades of spinning lures form clearly visible conical bodies of rotation with an angle of rotation, depending on spinner construction and velocity of retrieving, from 30o to 60o. The linear velocity of any spot located at R distance from the axis of rotation is v = 2πR/T, where T is an interim of one turn. If, say, the blade makes one turn per second and R = 0,5 cm, the linear velocity of this spot will be about 3 cm/sec. Generally, blades of spinning lures may make several turns per second, and rotation radii of spots may achieve 2-3 cm for lures of middle size. It means (for general principles, see Stojcev et al., 2011) that fish will see as flashing and colored only those spots, which are located as close as possible to the axis of rotation (with the lowest v).

For example, click here to see how Mepps spinners move (at the constant velocity) in the water.

According to the laboratory experiments (Gehres & Neumeyer, 2007; Stojcev et al., 2011), fish (goldfish, Carassius auratus) see fast-moving (7 cm per second) red and blue discs as colorless.

Figure given bellow shows some color pattrens desined on the ground of the foregoing rules.


These patterns can be used for face (convex) and back (concave) surfaces of the blades.

Curently, we are looking for world manufacturers to produce spinning lures with the foregoing and similar color patterns.
