People and objects changing from greyscale to colour is a wonderful way to depict change, be it in aspects of the world, or in the world you inhabit. But from the point of view of someone who’s accustomed to a greyscale world, it’d look uncannily, possibly horrifically, wrong.
Colour has been leeched from the world by Our Oppressive Grey Overlords, but a few members of the resistance hold objects which have retained their colour, and wield powers based upon that colour. Of course, once they’ve wielded their powers, the colour sticks around, so it’s pretty hard to be stealthy about it.

(It should be noted that “The Planck length is sometimes misconceived as the minimum length of spacetime, but this is not accepted by conventional physics, as this would require violation or modification of Lorentz symmetry.”, which makes Craig’s point largely irrelevant. I’m sure we’re all shocked. ~ T. Jones)
