How a Turbot sees your lure
Which lure colour a Turbot can actually see, at your depth and in your water. 2 cone types, peak 530 nm. Ranked contrast for 54 colours.
Scophthalmus maximus
Measured in the same family
No spectral measurement exists for this species. The cone peaks are a family-level substitution from other pleuronectiform flatfish. This is a coarser assumption than a same-genus one; the broad "which end of the spectrum" answer is reliable, the fine ranking between adjacent colours is not. Flatfish look UPWARD at everything, so the silhouette geometry is the one that matters for them — set the viewing direction accordingly.
Spectral sensitivity
| Cone peaks | λmax | Chromophore |
|---|---|---|
| Short | 455 nm | A1 |
| Medium | 530 nm | A1 |
| Rod | 505 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.

Questions people actually ask
Can a Turbot see colour?
Yes, but only just. It has 2 cone types, peaking at 455 nm, 530 nm, so it has a single dimension of hue where a human has 2.
Where does this data come from?
No measurement exists for this species. The cone peaks are a family-level substitution — reliable for which end of the spectrum, not for fine ranking.
