Black is not considered a pure color. It is the absence of all colors.
Here's why:
- Color is defined by light. When light hits an object, some wavelengths are absorbed, and others are reflected. The reflected wavelengths are what we perceive as color.
- Black absorbs all wavelengths of light. This means no light is reflected back to our eyes, resulting in the perception of black.
- Pure colors are created by a single wavelength of light. For example, red is created by the longest visible wavelength, while violet is created by the shortest.
- Black is not a single wavelength. It is the absence of all wavelengths.
Therefore, black is not a pure color but rather the absence of all colors.
