Technically black is not a colour and is the absence of light as someone earlier said, but if you're talking about clothes dyes then they are not true black so are shades of colour. Sometimes a bit brown, or even a bit blue, you know, blacks vary. True black absorbs all light and reflects none back (which is also why black things get hot in the sun and white things are cooler). Colour is the light that is reflected back. So grass is green because the plant absorbs all the other colours of the spectrum for photosynthesis and reflects back the green which we can then see. White things reflect back all the light. Here endeth the lesson! lol
