Best lure colours for largemouth bass, as its eye receives them
Dichromat, green + red. Strong on chartreuse/red separation, weak on blue. The model gives it 2 cone types, peaking at 535, 614 nm. At 3 m and noon, the top scorer in clear water is Chartreuse, Red craw, Firetiger, Shad, and in tannin-stained water it is Chartreuse.
What the model says about largemouth bass
- Clear, 3 m: highest 100 (Chartreuse, Red craw, Firetiger, Shad), lowest 35 (Blue).
- Green / algal, 3 m: highest 100 (Chartreuse), lowest 20 (Blue).
- Stained / tannic, 3 m: highest 88 (Chartreuse), lowest 15 (Blue).
- Muddy / suspended sediment, 3 m: highest 26 (Chartreuse), lowest 0 (Blue).
Colour by water type (3 m, noon)
Detection contrast, 0 to 100, from the same contrastScore() the Fish Vision Camera reports, viewed from 1.5 m. Capped at 100, so several colours tie at the top.

Dawn, dusk and night: when colour stops mattering
The model blends from cone vision to rod (brightness-only) vision as light falls, and a species with a better low-light eye holds colour longer. This is the share of rod vision the largemouth bass gets at 3 m, 0 meaning full colour and 100% meaning brightness only. Light levels are the ones The Fish uses.

Once the eye is mostly on rods, a lure is only a lighter or darker shape; hue no longer carries information, so scores in those columns are driven by brightness difference alone.

What this does not tell you
This is how visible a solid-colour lure is against the water behind it, not how likely a largemouth bass is to eat it. It does not model prey matching, patterns, flash, UV, vibration or mood. The model uses published cone peaks as Gaussian curves and a single light adaptation rule per species, which is a simplification. Inputs are fixed at 1.5 m viewing distance and a flat water column; change them in the Fish Vision Camera. Limits are listed under how it works. To see colour feed a feeding decision, run it through The Fish or browse the scenarios.
