Understand that the color we perceive an object to be depends on the wavelengths of visible light that the object reflects or transmits to our eyes.
Recall that visible light consists of a spectrum of colors, each corresponding to different wavelengths.
When an object absorbs all colors (all wavelengths) of visible light, it means no light is reflected or transmitted back to our eyes.
Since no light reaches our eyes from the object, it appears black, which is the absence of visible light.
Therefore, the observation when all colors of visible light are absorbed by an object is that the object appears black.
