How to Use the Fishing Lure Color by Depth Guide
Underwater, light wavelengths get absorbed at different rates. Long-wavelength red light disappears first, so a red lure can already look gray by about 16ft (5m) of depth, while short-wavelength blue and purple light travels much deeper before fading. Enter your target depth, water clarity, and weather, and this guide recommends the color family that will actually be visible to fish at that depth.
Murky water and cloudy weather both absorb light faster, so the calculator applies a light-adjusted effective depth that's deeper than the actual number you entered. Clear water and strong sunlight do the opposite, letting brighter colors work even at depths where you might expect them to fade.
At shallow depths, red and orange tones look like natural prey colors. At mid-range depths, high-visibility chartreuse and green tend to work best. At greater depths, color itself matters less than a strong backlit silhouette, which is why blue, purple, and black lures often outperform brighter colors down deep.
Frequently Asked Questions
Water absorbs long-wavelength red light first, so a red lure can look gray or black past about 5m (16ft) of depth. Shorter wavelengths like blue and purple travel much deeper before fading.
Cloudy days mean less light overall, so color fades faster at the same depth. Choose a brighter shade or a stronger silhouette color than you would on a clear day.
