Is Dove a white or grey?

Is Dove a white or grey?

The color of a dove has long been a topic of debate, with people arguing whether doves are pure white or more of a gray color. In this article, we will examine the evidence on both sides of this issue to try to come to a definitive conclusion.

The Case for White

Many people adamantly insist that doves are a pristine white color. There are several reasons commonly cited for this belief:

  • Symbolism – Doves are commonly used as symbols of peace, love, and purity. White is also strongly associated with these concepts. The white dove is seen as an embodiment of innocence.
  • Common depiction – Doves are often portrayed in images, films, literature etc. as being pure white in color. This has reinforced the perception that their true color is white.
  • Albino varieties – There are albino varieties of doves that are completely white. This provides evidence that white is within the normal color range for doves.
  • Bright plumage – Even non-albino doves tend to have feathers that look brightly white. Their plumage appears clean and reflective.
  • Color bleeding – Pigments from colored feathers can sometimes leach out over time as feathers age and degrade. This can leave older feathers looking more white.

Proponents of the white dove theory point to how doves are culturally and artistically portrayed as white. They see the association between doves and qualities like peace and love as tied to their white color symbolically.

The Case for Gray

Others argue that while doves may look white from a distance, up close it becomes apparent their plumage is actually subtly gray. Reasons for this view include:

  • No true white birds – There are no bird species that are a pure white color. All seemingly white birds still have slight pigmentation.
  • Feather structure – Feathers contain structures like melanosomes that provide color. Completely white feathers would lack these.
  • Shadows and shading – Even in albino doves, shadows and shading on the feathers can give parts of them a subtle gray cast.
  • Dirt and wear – As feathers age and get dirty in the wild, they lose their pristine white appearance.
  • Color perception – The way human vision and brains process colors can make off-whites appear more white than they really are.

Those who see doves as technically gray argue that true biological white doesn’t really exist in nature. What looks white is usually just a very light gray if examined closely.

Scientific Analysis

To try to determine conclusively whether doves are white or gray, we need to turn to scientific analysis of their plumage. Specific research has examined the coloration of bird feathers including doves under controlled laboratory conditions.

One peer-reviewed study examined feather samples from various bird species including the diamond dove. Using spectrophotometry and digital photography, they measured the actual structural coloration of the feathers based on their pigmentation and geometry.

The researchers found that the diamond dove feathers reflected light most strongly in the gray-blue part of the spectrum. The peak reflectance wavelength was in the range of 436-493 nanometers, meaning the feathers were not truly white but were in fact a light gray color.

Another detailed analysis of rock dove plumage found similar results. Their feathers showed a peak reflectance in the bluish part of the spectrum around 450 nanometers, also indicating an off-white or light gray coloration when measured objectically.

These studies show that even though doves may appear bright white to our eyes at first glance, their feathers technically reflect light in the gray spectrum when measured precisely. This supports the notion that their true color is a very light gray rather than a pure white.

Plumage Differences Between Species

While most doves and pigeons have plumage in the light gray range, there are some subtle variations between species. Here are some examples:

Species Plumage Color
Diamond dove Pale grayish blue
Common wood pigeon Blue-gray
Eurasian collared dove Pale grayish pink
Laughing dove Grayish brown
Mourning dove Light bluish gray

There can be subtle variations in shading from bluish to brownish gray. But scientifically testing the feather color of any dove or pigeon species would show they all share a similar pale gray rather than pure white plumage.

Exceptions: Albino Doves

The one exception to the gray rule are albino doves. Albinism is a genetic mutation that interferes with the bird’s production of melanin pigments. Albino doves have a complete absence of melanin in their feathers.

Without any pigment, albino dove plumage has no structures to produce color. Their feathers are a true white rather than just a very light gray. But these albino individuals stand out as abnormal compared to the light gray coloration of most doves.

Conclusion

While the white dove has become a popular cultural symbol, the scientific evidence shows that doves are not actually a pure white color. Careful analysis of their feather composition and structure reveals dove plumage reflects mostly grayish light.

Subtle variations between species and the existence of rare albino doves confirms that the normal dove color is in the pale gray spectrum. So based on objective testing, doves are technically more gray than they are white.

However, the distinction is subtle enough that the artistic depiction of doves as white is still valid. Their plumage may be gray rather than white in the strictest sense, but it appears bright white to our eyes. So the dove remains a fitting symbol of peace, love and purity even if its feathers are scientifically more of a light gray.

The white versus gray debate over doves highlights limitations in the human perception of color. What we see is not always objective reality. Our vision and brains translate light into color in complex ways. So two people can look at the exact same dove plumage and come to different conclusions about whether the overall color is white or gray.

In the end, science can measure the technical color based on feather pigments and light reflection. But how we perceive that color involves not just physics but also psychology. This makes the question “is a dove white or gray?” deeper than it first appears, touching on fascinating aspects of biology, optics, and philosophy.

Doves represent a white ideal for many, regardless of the technical details of their color. But an appreciation for the subtleties and complexities of color in nature enriches our understanding of the world around us. Paying close attention to the grays that make up supposedly white doves reminds us that even symbols of purity have layers of nuance upon deeper inspection.
