How a Skipjack tuna sees your lure
Which lure colour a Skipjack tuna can actually see, at your depth and in your water. 2 cone types, peak 485 nm. Ranked contrast for 54 colours.
Katsuwonus pelamis
Measured in the same family
No spectral measurement exists for this species. The cone peaks are a family-level substitution from the tunas of the genus Thunnus. 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 | 425 nm | A1 |
| Medium | 485 nm | A1 |
| Rod | 483 nm | A1 |
Rods do the work at dawn, dusk and night — which is when most people fish.

Questions people actually ask
Can a Skipjack tuna see colour?
Yes, but only just. It has 2 cone types, peaking at 425 nm, 485 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.
