What would be the implications if a whole new primary color was discovered?

Please humour me as I know it's very far fetched but for arguments sake lets just say a new color was discovered that is actually invisible to the eye until it's under certain atmospheric conditions. Would there be any major implications for this? I ask because if you try to imagine what a new color would be like it's almost impossible to conceive so for this reason it must have some far reaching implications.

Most of light is invisible to us. The colors we see are part of the narrow "visible light" spectrum. Our sun pours out plenty of this non-visible light, both in the ultra-violet (smaller waves than we can see), and in the infra-red (larger waves than we can see) spectrums, and many Earth creatures do see these other forms of light. How their brain perceives these "colors" is something we can't know, but they do see them. What we call the different colors is simply the distinct subdivisions we discern between different parts of our visible spectrum. "Discovering" a new color has no meaning in this context, as color is not a matter of existence, but of definition. If we simply carve out some section of the non-visible specturm and define that as our new color, that's that. Their existence, however, is already known fact.
