Bird Vision will take your waterfowl decoys to the next level with an even more realistic look. Birds enjoy sharper vision than us, allowing them to see in the UV spectrum, which we cannot see. Your decoys are absorbing UV and not reflecting UV. This causes your decoys to look unrealistic, not the right color like realistic feathers. Now that has changed with the introduction of the patent pending Bird Vision UV Reflective Decoy Paints! With this revolutionary UV reflective Decoy paint, you can repaint your old decoys to make them look more realistic to waterfowl. UV Bird Vision decoy paint matches the UV reflectance of feathers in a full range of light to birds, which includes (UV) ultraviolet. Birds see 4 primary colors(red, green, blue and ultraviolet). All colors visible to birds are blends and combinations of these 4 colors. Humans cannot see UV this 4th color as we do not have the 4th cone in our eyes.
