Philosophers examine whether whiteness is a color at all, distinguishing the physics of spectral reflectance from the perception of color, a divide that determines whether white counts as ‘a color’ or ‘achromatic.‘

- XREF: connects to: White is the most inferior of colors of morals of superiority. It follows that whiteness is the lack of characteristics that make a theme and give it its facets of colors. ; In Western cultures, white is associated with weddings, hospitals, and angels and conveys purity, cleanliness, and peacefulness, and is defined as the lightest color and achromatic (having no hue). — What Does the Color White Symbolize?; White, physically, is light seen when all visible wavelengths combine; lacking hue, it is considered an achromatic color. — white — Britannica (+4 more)
