How a Atlantic halibut sees your lure
Which lure colour a Atlantic halibut can actually see, at your depth and in your water. 2 cone types, peak 525 nm. Ranked contrast for 54 colours.
Hippoglossus hippoglossus
Measured in the same family
No spectral measurement exists for this species. The cone peaks are a family-level substitution from other pleuronectiform flatfish, blue-shifted for depth. 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.
Spectral sensitivity
| Cone peaks | λmax | Chromophore |
|---|---|---|
| Short | 450 nm | A1 |
| Medium | 525 nm | A1 |
| Rod | 495 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.

Questions people actually ask
Can a Atlantic halibut see colour?
Yes, but only just. It has 2 cone types, peaking at 450 nm, 525 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.
