I have a sneaking suspicion that all the available colour experiences are utilised in the brain. If one of the three stimulating sensors is deficient then the available sensations are "distorted" down to fully occupy the limited (flattened) colour space. Acquiring a new sensor input through gene therapy or some such, would probably result in some things of the newly sensed colour initially appearing brighter versions of an existing colour, before eventually the colour space became "(re)-inflated" with increased gradations becoming more common and more objects shifting into different colours.
So, the sensations already exist but your brain needs a bit of time to learn how to best use the extra information.
