Our video technology is designed to capture and reproduce what humans can see. If all humans were red-green colourblind, we would only have designed our videos to capture green-blue images, and our TVs would only output green-blue images. To us, they would look like perfect reproductions of the world. In that world, you would be arguing there are only two colours. Yet, the image on those green-blue TVs would obviously not be an accurate reproduction if viewed by a person with normal RGB colour vision from our world. Similarly, compared to Geordi La Forge, we are all colourblind. He can distinguish thousands of different wavelengths of light independently, and to him our current RGB videos look nothing like the reality they attempt to depict, due to all the colours they throw away.
