What is the meaning of 'color used in the image of the new coronavirus', which means that the color of the virus is different from that of the new coronavirus?
News on the new coronavirus (SARS-CoV-2) is reported daily in large numbers, and 'new coronavirus images' are sometimes seen on TV programs and on the Internet. The 'colors' used in such new coronavirus images are determined by the creator of the images, and are not standardized.
Scary red or icky green? We can't say what color coronavirus is and dressing it up might feed fears

Speaking of the new coronavirus, many people will associate the image with many protrusions protruding from the spherical body as shown in the image below. In the image below, the color of the gray body is red protrusions ...
Looking at another image, the whole is painted green.
The reason that the color of the new coronavirus differs depending on the image does not mean that there is a difference in the knowledge that the author has. Actually, even if you look at the images published by the

Weaving points out that the color of the new coronavirus is so different because it is difficult to know the color in a microscopic world. Humans rely on light to perceive color, and some of the light that strikes the target object is absorbed, and the rest is reflected and reaches the eye, perceiving the color. For example, when you look at an apple, you feel 'red' because it absorbs many of the wavelengths of light while reflecting the red wavelengths.
However, if the target object is too small, light will not be an effective tool for recognizing the object. Because the virus is so small, looking at the virus using an optical microscope is like 'searching for ants from a soccer stadium using a searchlight.'
Scientists were able to see viruses after the development of electron microscopes, which use electron beams to observe objects instead of light. By using an electron beam whose wavelength is much smaller than that of visible light, it has become possible to observe the structure of viruses that cannot be seen using light.
However, electron microscopes do not use light to observe the object, so they cannot know the 'color' of the object. For this reason, the virus seen with an electron microscope is actually black and white as shown in the following image.

However, 'Images that are just unfamiliar chunks of gray will not be convincing or emotional media content,' said Weaving. In fact, in past news reports on the outbreak of the virus, 'images with a virus-related impact' were used more often than images of the virus itself.
The 1995 outbreak of the Ebola virus often used images from a group of Western health professionals working in Africa to end the epidemic. Weinging also said that in the news of the discovery of the human immunodeficiency virus (HIV) , 'images of young men who developed AIDS and were weakened' were often used.
In this new coronavirus, the symptoms themselves are similar to those of the cold and flu, and the majority of the deaths are from the elderly, so the impactful images are relatively few. Therefore, it seems that images of the new coronavirus that are colored and have a high-impact appearance are often used in news and other media.

However, toxic coloring of the virus can overwhelm the threat of the virus or panic people. Weaving therefore recommends expressing the virus as a 'gray presence', as seen in an electron microscope that observes the virus.
'Graying the virus has several distinct advantages. First, it applies to the scientific notion that there is no color where light cannot reach. The image is that it reduces the threat of the virus, and without the red bumps and green body it would not look like a hostile intruder in science fiction fantasy, 'said Weaving, the new coronavirus being gray. Claimed that it should be expressed.
