My daughter had to write an essay about the intersection of arts and science as part of her application to the UW Honors College. She wrote about our imagery of the Covid-19 virus and how nearly every single visual portrayal of the virus shows it as red. Or with red coronas. While in point of fact, the virus is actually smaller than the wavelength of visible light meaning that it, by definition, has no color, and cannot have a color. So why do we color the virus red? No scientific reason, it’s actually unscientific to do so. But in the arts we have lots of popular imagery of red as the color of danger going all the way back to the Odyssey.
