    Could there be an undiscovered color that our brain is not aware of?
    Has anyone heard of "impossible colors"? Does that mean the impossible bluish-yellow and reddish-green are
    the undiscovered colors that we cannot see?
    And are those colors impossible to exist or impossible to see?

    What people call colours is pretty subjective. The fundamental issue is the frequency of the em radiation, a measurable quantity. The subjective labelling of such photons as "red" or whatever matters not a toss. Most people see the same range of frequencies which is but a very narrow band of the spectrum but whether you call what you see red, rouge or sfhggh is irrelevant.

    Our eyes can only see a small range of frequencies (other animals can see into the ultraviolet and infrared). Also, we create all the colours we see from just three types of receptors with overlapping sensitivity. Other animals have different numbers of receptor and so probably see colours that don't exist for us.

    And of course, people with various forms of colour blindness see fewer colours than most.

    I have seen illusions that create new colours like yellow-blue. It is quite weird.

    If you are interested in colour (or humour), this is worth a read: Color Survey Results | xkcd

    Maybe I'm being too much of a reductionist in this thread but as far as my work goes you trust the spectrometer and Mie theory. Colours? Pfft...

    Allegedly some women, albeit very few, might be able to see a wider array of colours than men. The Mantis Shrimp has 16 types of cones, which enables it to see an obscene array of colour. Here is a link to a RadioLab podcast where they discussed colour.

    Colors - Radiolab

    Edit: So according to RadioLab, there are a lot of colours just like the ones you are describing that, in fact, do exist - but are merely beyond our sense of vision's ability to perceive.

    That sums it up. How we see radiation is limited. descriptions are Subjective.. What's interesting is that direct translation between languages is not precise when it comes to colours. I find this when reading French and English. Reddish colours and bluish green colours have fuzzy translations.

    But the important question is, do sfhggh cars go faster than red ones?

    They go so fast the reflected light of them is sfhggh-shifted so much you can't see it and they are effectively invisible

    Right down into the infra-sfhggh spectrum.
