The interesting thing is that so much of color (and vision in general) is software, not hardware. Our eyes don't see color and light the way we we perceive them at all, it is a composite of multiple sensors each doing different things. Colors like magenta are almost entirely constructed by our brains in software because we don't physically register them but recognize their presence. Then there is the element of how we define colors at all - some languages have no word for blue, for instance. People can see and distinguish the color but without context along the spectrum they way they understand the color is definitely influenced by lots of contextual factors. So from that perspective, we certainly do not all perceive colors the same.
