Technically, black is the absence of color. We only see certain colors because those colors are reflected (i.e. they aren't absorbed). We see black because the substance absorbs all color wavelengths, and hence no colors are reflected back.

Combining a large number of colors will yield a black "color". Try Red, Orange, Yellow, Green, Blue, Indigo, Violet.

This is truly one of the most complex questions:

Black is an absence of light. I would define light as some segment of electromagnetic radiation, but I am not sure how, it depends on who or what is detecting the light.Color will vary depending on on individual, some people are colorblind and cannot distinguish red from green. Eyes contain rods and cones, which respond to light differently, some people are colorblind, some animals see different frequencies, insects see ultraviolet. Films also see differently from animals and people.

The only truly black object may be a black hole (and even they may emit energy at times, I believe)

Colored objects absorb some light frequencies over others. Objects that are black in daytime, absorb much of the light that hits them. Color is a complex combination of the frequencies of the light hitting the object, the intensity of the light, the materials of the surface of the object, and the "receiver."

Also colored objects may not contain pigments, but reflect or reflect light in "unusual" ways: diachronic glass, butterfly wings, glass prisms, polarized lenses, opals.

If you are painting or doing artwork, there are many ways to get colors for black, usually black is not a good choice, because it is "dead" looking. Look for books and sites on "color theory" it will depend on the media you choose also.

Also colors don't always mix. Chemicals can react with one another. Dyes will vary in effect based on mordants, fibers being dyed.

If I remember correctly, black is not a color, but the total absence of color. If you mixed all the primary colors, you would get white.

Black is the absence of color and light in the scientific sense so no colors can be combined in a spectrum to create black. White is the combination of all colors. However if you mean with like markers or something try combining them all.

Black color is the combination of all other colors. White is the absence of any color.

If u mx Cyan, Magenta and Yellow in same ratio u will get Black color. U can easily get black color by firing ur clothes, or any other material u own.

If you are talking about art (as in mixture of paints, etc.) then all the colours mixed together would give you black. However, as your question is under the physics category, I would have to say that black is the absence of all colour, and if you were to combine all colours, you would have white.

red and green make brown
if you try mixing a bit of blue in, you should get black
