The absence of color is often referred to as ‘black.’ In the context of visible light, when no wavelengths are reflected back to our eyes, we perceive darkness or blackness. This lack of wavelengths means that there is no color to be seen.
In terms of pigments, the absence of color can also refer to ‘white,’ as white is the result of all colors of light being reflected simultaneously, essentially masking the individual color properties. It’s interesting to note that while black absorbs all colors, white reflects them, creating a balance of color absence and presence.
