Is black a color or lack of color?

Black is the lack of color. The colors we see are a reflection of a specific frequency of light. When light, which is composed of many different frequencies, hits an object, that object absorbs those frequencies. If they absorb all of the frequencies, the color you see is white. If they absorb most, but not all, then the frequencies they don't absorb are reflected, thus giving you the color you see. Take, for instance, a piece of red construction paper. That paper absorbs every color frequency but red, so it reflects red. If an object reflects all frequencies, then the color you see is black. So technically, black is an absence of color in an object. Um, it's been a while since I took physics, but I think that's how it works. If I'm wrong, someone please correct me.

actually white is the lack of color. If you mix a whole bunch of colors together of paint...you will get a grayish color..normally. Black is the opposite of white..it is a color..not many are darker then it.

in my opinion i would have to say that black is a color. i find that gray is being lack of color.
