Colour - the way we see

Colour is not an property of what we are looking at – it is something created in the brain as a result of the way your eyes interpret wavelengths of light. Colour is an invention of the human brain. Without our eyes, there is no such thing as colour – so everything must be in the equivalent of greyscale. Were there aliens, colour might not be one of their senses and they might have an additional sense or completely different senses from our five…

What would it be like to see colours differently? Or not see colour at all?
