New Colour

[Rharris9585]

Is it possible that there is a colour that we haven't yet discovered or know anything about?

[soonny]

YES.

 

You have to know how our human eyes perceive light as it is. The sun emit a huge range of wavelenghts of light but the human eyes can only pick up a small range of it. Light such as infrared or UV light cannot be seen because it's wavelength is either too short or too long. And that goes for other wavelengths of light as well.

 

So if you're asking if there's another colour we haven't discovered, I would say yes because we couldn't see them! But that's also very unfortunate because the only way we could ever see these lights is with the help of devices but not with our human eyes.

Is it possible then that there is a colour (visible to the human eye) other than those in the rainbow that could still remain undiscovered?

[fantastical]

No. Every colour that we know to exist (the ones we can "see" to site soony's response) is a combination, or mixture, of certain shades of colour on the visble part of the colour spectrum.

So really, there are an infinite amount of colours possible, each varying to some degree of the certain shades on the visible part of the spectrum.

R-red
O-orange
Y-yellow
G-green
B-blue
I or V - indigo or violet

[jenstar]

In a sense, yes. There are an inifinite number of possible colours, but many of them are so similar to one another that we can't distinguish between them.

[bernardo]

No.

[magicdice]

no

there aren't colours to discover, but wavelengths of electromagnetic radiation, so there's a finite number within the visible light region, all of which we've seen.

[landie]

Colours within the visible spectrum are, as previously stated by others, all contained within the rainbow with miriad subtle changes from one to the other.

On top of this you may have tints or shades of a colour. Tints are obtained by mixing a colour with white in different ratios. Similarly shades of a colour can be achieved by mixing with black.

So whether pink (a tint of red) is a colour or not depends on your point of view but I dont think it forms part of the rainbow.
