Why Some Lure Colors Stay Visible Deeper Than Others
Part 5 of the Soft Plastic Lure Color Guide
Every color we see is a wavelength of light. Water absorbs these wavelengths at different rates as depth increases. The key principle is simple: longer wavelengths disappear first; shorter wavelengths travel farther. This single principle explains most lure color behavior underwater.
Fishing Lure Color Wavelength Reference
| Color | Wavelength (nm) | Depth Visibility | What Happens |
|---|---|---|---|
| Red | 620–750 | Shallowest (0–3 ft) | Absorbed first — functions as dark/black at depth |
| Orange | 590–620 | Shallow (0–6 ft) | Fades quickly in murky or deep water |
| Yellow | 570–590 | Moderate | Retains some visibility in clear water |
| Green | 495–570 | Good | Visible at moderate depth; blends with vegetation |
| Blue | 450–495 | Deepest | Penetrates furthest; visible in clear, deep water |
| Violet/UV | 380–450 | Variable | UV-enhanced colors can extend visibility beyond normal range |
Why Red Becomes Black at Depth
Red has the longest visible wavelength and is absorbed by water first. A red lure that looks bright in your hand may appear dark brown or near-black to a fish at 10+ feet. This is actually useful — at depth, red functions as a silhouette color without the “artificial” brightness that sometimes triggers refusals in clear water.
How to Use This
- Shallow water (<5 ft): All colors remain functional — red, orange, yellow are viable
- Mid-depth (5–15 ft): Shift toward green, chartreuse, white, or dark silhouettes
- Deep water (15+ ft): Blue, purple, and UV-enhanced colors outperform warm tones
- Any depth in stained water: Contrast and silhouette dominate — exact color matters less
