How red disappears underwater – and why it matters🇬🇧

Red is the first color to disappear as you fish deeper. At around 5 meters, a red lure looks grey or black to a fish. By 10 meters, the color is completely gone. This matters because many anglers choose red lures for deep jigging or trolling, thinking red signals "blood" or "injured prey." In reality, the fish cannot see the red at that depth – the lure just looks like a dark silhouette. The color spectrum underwater works like this, from first to last to disappear: red (gone by 5 m), orange (by 10 m), yellow (by 15 m), green (by 25 m), blue (visible deepest). UV and fluorescent colors keep their visibility longer than non-fluorescent versions of the same shade. Practical takeaway: Use red lures in shallow water (under 3 meters) where the color is fully visible. For deeper water, switch to blue, purple, green, or UV-reflective lures. If you want that "wounded prey" effect in deep water, use a lure with a slow, erratic action instead of relying on color.
