what is a colour?

Question

i mean what is a colour?
What makes things coloured? and what decides which colour?

Answer 1

um...god

Answer 2

Color vision is the capacity of an organism or machine to distinguish objects based on the wavelength (or frequency) of the light they reflect or emit, and arises through an appreciation of the distribution of light intensity over the visible spectrum (450-700 nm). A 'red' apple does not emit red light. Rather, it simply absorbs all the frequencies of light shining on it except the frequencies we call red, which are reflected. An apple is perceived to be red only because the human eye can distinguish between different wavelengths

Answer 3

Any matter you take, it has the substances responsible for its colour. When sun light or any artificial light falls on the matter, the substance responsible for the colour (pigment) absorbes the light except light with cerntain wave length. The omitted light with certain wave lenght reaches our eye and it recognises as certain colour. Eg. take green leaf of a plant. It has chlorophyll (the green pigment). Sun light falls on it. The sun light is made up of 7 coloured light in the visible range and lights of invisible ranges also (lilke UV and IR). The leaf absorb all the colours except green. Thus the leaf relects the green coloured light. The leaf shows the green colour. If you see the leaf in dark (with out sun's light), it is a black material.

Answer 4

Color or colour (see spelling differences) is the perception of the frequency (or wavelength) of light, and can be compared to how pitch (or a musical note) is the perception of the frequency or wavelength of sound.

It is a perception that, in humans, derives from the ability of the fine structures of the eye to provide the brain with differently filtered analyses of a view (usually three). The perception of color is influenced by biology (some people are born seeing colors differently or not at all; see color blindness), long-term history of the observer, and also by short-term effects such as the colors nearby. (This is the basis of many optical illusions.)

The science of color is sometimes called chromatics. It includes the perception of color by the human eye, the origin of color in materials, color theory in art and the physics of color in the electromagnetic spectrum.

Answer 6

Color exists only in our head. With out our brain’s ability to interpret the intricate and individual way light is reflected off every object in nature, the world would be entirely colorless.

Objects themselves have no color, nor does the light reflected by them.

What we see as color is actually the result of the way different wavelengths of light stimulate certain parts of our brain’s visual system.

Answer 7

Light makes color

Depending on what kind of light an object aborbs determines color.

Whatever color is deflected is the color we see. A red object absorbs all light except red, for example.

White is the reflection of all colors, and black is the absorbtion of all colors.

Light reflects colors...
