How a Common snook sees your lure
Which lure colour a Common snook can actually see, at your depth and in your water. 2 cone types, peak 535 nm. Ranked contrast for 54 colours.
Centropomus undecimalis
No spectral data exists — estimated
NO direct spectral data could be located for this species. The cone peaks below are an estimate from its habitat optics and its phylogenetic position, not a measurement. Use the water and depth results — which do not depend on the species — with much more confidence than the colour ranking.
Spectral sensitivity
| Cone peaks | λmax | Chromophore |
|---|---|---|
| Short | 455 nm | A1 |
| Medium | 535 nm | A1 |
| Rod | 500 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.

Questions people actually ask
Can a Common snook see colour?
Yes, but only just. It has 2 cone types, peaking at 455 nm, 535 nm, so it has a single dimension of hue where a human has 2.
Where does this data come from?
No direct spectral data could be located. The cone peaks are an estimate from habitat and phylogeny, not a measurement. Trust the water and depth results far more than the colour ranking.
