Going one step further, really nothing is true colour. Colour is subjective, and relational, we evolved to compensate for different sun brightnesses and angles, different sky colours. So the constant demand for 'true colour' images from space are not only frustrating, they are meaningless. You can provide images with very exacting wavelength information, but you can't make them true colour because that doesn't exist.
