I should imagine that they simply shift the entire spectrum of electro-magnetic radiation collected into the visible spectrum. There may be some compression or expansion as well to get the maximum range of colours.
Sounds exactly what they are doing tbf.

You said they are guessing at what colour it 'might' be. They aren't, it isn't any colour because the wavelength of the electro-magnetic radiation doesn't fall within the visible spectrum. If it's not on the visible spectrum then by definition it has no colour.

This is the definition of colour.
