How do we know that there are no more colors that are undiscovered?

Question

Like a primary color (red, green, yellow, orange, blue, purple.)

When I say primary colors I mean the IMPORTANT colors...idiots I think I know my colors

Answer 1

It is impossible to prove the no more of something will be discovered, but this is why we think we have found all the colors.

A color corresponds to a certain wavelength of electromagnetic energy. Visible light varies from about 350nm (purple) to 750nm (red). Energy outside of these wavelengths manifests itself as another form of light: radio, microwaves, x-rays, heat, ultraviolet, etc. When we divide a mixture of all wavelengths up into a rainbow, we can see the entire set of colors visible to humans.

Incidentally, only red, yellow and blue are primary colors.

Answer 2

because colors are just different frequencies of light that are part of the Electromagnetic spectrum. Visible light is only a small part of the spectrum.
So basically sound, radio waves, light, X-rays, gamma waves are the same thing just at different frequencies.
since we know the frequency range of the visible spectrum (3 x 1012 - 4.3 x 1014 Hz) we are able to create light using these frequencies as a guideline and go through all possible colors pretty easily.

There are invisible colors like infrared and ultraviolet, and probably there are some other types of radiations outside of the currently known frequency range. But most likely it wouldn't be "new colors".

Answer 3

Don't you mean red green and blue are the primary colors?

The color spectrum from red to violet is continuous. You can keep on subdividing a rainbow into finer colors even though there only 7 basic colors.

Then you can blend these colors to make ones that aren't in the rainbow like cyan and purple. Then you can vary the brightness to make light and dark variations.

To get realistic pictures on computers requires at least 16 million colors.

Answer 4

There are more colors, only the human eye isn't developed enough to see them... That's kind of sad. And by the way, red, blue and yellow are the only primary colors... Everything else is made up of those three.

Answer 5

Lol, this question is showing up the ignorance of the asker and the respondants!

Let me clarify, there are three additive colour primaries RED GREEN and BLUE. These work with light

And three subtractive primaries CYAN YELLOW and MAGENTA these work with paints.

orange and purple are not primary colours like the asker assumed!

Anyway, we only see a small amout of the electromagnetic spectrum with our eyes, it is the cones in our eyes that convert waves into 'colours' that we 'see'. They do not exist like this in life, and neither do sounds.

In a rainbow, white light is refracted into its components, we see ones that we are able - and cyan is defintely in there!

Back to the question, the human eye is only able to 'see' a narros range of about 16 million colour shades. Other animals and mechanical devices can of course see a wider range.

Answer 6

Colors are actually caused by light. All of the colors in the world are caused by light being absorbed or reflected by objects. For example, leaves are green because they reflect green light and absorb everything else. As light moves beyond the edges of the visible spectrum, it turns into infrared rays at the lower end and ultraviolet rays at the higher end, neither of which you can see. There are no undiscovered colors to see because there is no more new light that we can actually see.

Answer 7

The human eye has structures (rods) that are specifically for receiving one of only three colors, which combine to make all the colors we can see. All combinations of these colors have been created. If there are other colors, human eyes cannot detect them.

Answer 8

We know the chemistry of the eye. There are only three receptor pigments for color vision.

Answer 9

I see lots of UV colors as well as infra red light. All humans have the equipment to do so, but most of us will not learn how to use it.

Answer 10

No, wait, I have a plan.


With light it is a simple matter. And the RGB

used with PC monitors are based on that.

But with physical colors or pigments, the

variation are, for all practical purposes, infinite.

Why art(paintings) have so many luscious

tones.
