When you Mix all visible colours, you get only Black colour. Why not some other Colour?

Question

All the colours in the visible spectrum (VIBGYOR) forms black colour while mixed together.

Answer 1

the pigments absorb certain colours and reflect and transmit others .
these reflected colours of light give the pigments their colour.
so a red pigment absorbs all colours other than red and hence appears red.
this holds for other colours as well. hence when we mix all the colours we get black because then all colours of light are absorbed and hence no colour is reflected for which it appears black
by this i mean that red absorbs all colours ecept red blue all colours except blue and so on.
now blue is absorbed by red pigment and red is absorbed by blue and so on
hence if we mix all the pigments we get black colour

Answer 2

You are referring to inks or dyes.

Inks or dyes work on the principle of colour subtraction. There are two types. Inks used in printing are transparent - the colour you see is reflected from the page and the ink "subtracts" certain colours from this. Other dyes are reflective. The dye absorbs some colours and reflects the rest.

If you add all of the available colours in either case it is clear that you will "subtract" all of the visible colours, leaving black.

In fact with inks for printing - of which cyan, magneta and yellow are used - mixing all of them actually gives mucky brown (very dark, not quite black). As a result, black ink is also used to improved image quality.

Answer 3

WRONG
When you mix vibgyor you get white not black.Why not some other part is bit difficult to explain.Each colour corresponds to some frequency in visual spectrum.When you mix all of them you get a sensation of white .That's how our brain interprets it.

Answer 4

you know black is not a "colour"....


it absorbs all wavelengh of the coloured region ...you cantsee a thing

Answer 5

when you mix all colors together you get white.
