Based on UV imaging and UV-Vis spectroscopy, we have reformulated only UV reflective colors.Įffectiveness How much of a difference does UVision make?Įxperienced hunters who have used our products have noticed a difference in the way ducks and geese respond to decoys with our paint. Darker browns and black do not reflect UV, nor do the greens, blues or reds. Generally it is the lighter colors: whites, tans, and grays. No, not all waterfowl feathers reflect UV. Sillosocks are now made with UV reflecting heads. These two areas must be repainted in order to match the reflection of waterfowl feathers. Also, the gray paint on your windsocks should reflect some UV, but typically do not. Tyvek does reflect UV, but windsock heads, either plastic or coroplast, do not. How would this paint work for silhouettes or windsocks? The paint has been formulated to have the proper amount and type of UV reflectance to match the feather's reflectance. Parker Decoy paint with UVision has been formulated with non-yellowing paint that is opaque so that the underlying decoy shouldn't be exposed to UV if it is properly and evenly applied. These are the reasons why virtually every exterior paint is great at absorbing UV because coatings scientists want the paint to absorb UV to protect the substrate and the polymer binder of the paint. These paints absorb UV light for two reasons: 1) because the white pigment that most strongly reflects the visible wavelengths that humans see also strongly absorbs UV, and 2) to protect the paint from yellowing/oxidizing. Yes, standard decoy paints don't have UV reflection (other than a small baseline). Does the paint on regular decoys just not reflect UV light? But we know that they see UV and that many of their feathers reflect UV. Science knows a little about the former and even less about the latter. It's impossible to know right now exactly what a bird sees because color perception is part eye structure and part brain circuitry. We can not see one of the colors that they can see.įor humans, if you had a white object and removed the blue component, it would appear yellow (follow the Exploratorium link to convince yourself). We think it would be closest to someone describing what red looks like to a color blind person. So the birds don't see "black decoys" if only the UV is missing. Birds see all the other wavelengths that we see in addition to UV. This is a common conclusion that many people reach after seeing our UV images. So conventional snow goose decoys really look black to geese? If an object glows brightly under a black light, it is absorbing UV. Some people mistakenly call fluorescent paint UV paint but it isn't. Blaze orange and other fluorescent colors do the same thing, just at different wavelengths. That's why a white t-shirt seems so bright under a black light, it takes the invisible UV and converts it to visible. Objects that glow under a black light are fluorescent - they absorb the UV and re-emit it as visible light. When our T-shirts glow under a black light, we are not seeing UV reflection. You’d need UV imaging equipment to see the UV light coming off a black light. This is the violet light we see when a black light is on. Black lights also emit a small amount of visible light near the lower end of our wavelength range. Can't a normal black light be used to test for UV reflection?Ī normal blacklight does emit UV but our eyes can't see it. Since the wavelength is not affected by reflection, we are still unable to see them and the surfaces do not look any different to us. They simply reflect the UV wavelengths rather than absorb them. Optical brighteners that are used in fabrics and detergents are based on this same effect. Fluorescent paint absorbs the UV portion of light and re-emits it at another wavelength – one that can be seen by humans. Isn't basic fluorescent white paint the same thing?įluorescent paint which looks bright under a black light is not the same thing as UV-reflecting paint. Only by using UV imaging equipment will you be able to see the difference. The colors of our paints will appear normal to human eyes but will possess the UV reflection appropriate for that feathered area of the bird. Parker Decoy Paint with UVision looks and acts like normal oil based paint. UVision Technology Does the paint look like normal flat paint to us?
