Ask a scientist and you'll get a reply based on physics: “Black is not a color, white is a color.” Ask an artist or a child with crayons and you'll get another: “Black is a color, white is not a color.” (Maybe!) There are four sections on this page that present the best answers.

White is not defined as a color because it is the sum of all possible colors. Black is not defined as a color because it is the absence of light, and therefore color. In the visual art world, white and black may sometimes be defined as distinct colors. This is different from the concept of spectral color in physics.

If color is solely the way physics describes it, the visible spectrum of light waves, then black and white are outcasts and don’t count as true, physical colors. Colors like white and pink are not present in the spectrum because they are the result of our eyes’ mixing wavelengths of light. White is what we see when all wavelengths of light ...

en.wikipedia.org/wiki/Color

The color that a surface displays comes from the parts of the visible spectrum that are not absorbed and therefore remain visible. Without pigments or dye, fabric fibers, paint base and paper are usually made of particles that scatter white light (all colors) well in all directions.

One thing is certain: White is not a spectral color. Beyond that, people argue. People who ascribe to additive light theory (e.g., the manufacturers of your computer screen) are apt to say that white is a color but black is not. People who ascribe to subtractive light theory (e.g., artists) are apt to say that black is a color but white is not.

Discussion red green blue. Color is a function of the human visual system, and is not an intrinsic property. Objects don't have a color, they give off light that appears to be a color. Spectral power distributions exist in the physical world, but color exists only in the mind of the beholder.

Color perception, like sound perception, is a complex subject involving the disciplines of psychology, physiology, biology, chemistry and physics.When you look at an object and perceive a distinct color, you are not necessarily seeing a single frequency of light. Consider for instance that you are looking at a shirt and it appears purple to your eye.

The Olympus Microscopy Resource Center Microscopy Primer explores many of the aspects of visible light starting with an introduction to electromagnetic radiation and continuing through to human vision and the perception of color. Each section outlined below is an independent treatise on a limited aspect of light and color.
